Thanks for the info rev_les but its the wrong connection you mention. I do have that particular rectangular 10 pin but not in use, no CC. Guess I'll take a picture like others mentioned. I'll be back......rev_les said:
Either someone stole relay or going nuts....
Can you believe this crap! Been working on my 95 Astro AWD that has been plagued with all kinds of wiring issues from some mad butcher. To make a long story short a relay has disappeared from the engine compartment driver side firewall above and left back side of fuse box. I'm positive there was one there 2 weeks again when last working on this bugger. Has 5-6 wires with plug/socket just hanging! Definitely not the fuel pump or oil pump relay that are located on the right side above heater box. Can someone with the same model & year post the relay part number and what it's purpose is? I was suspect on why this friggin thing wouldn't start today, just fire up and die, time after time. I'm hoping this MIA relay is the reason for no start and when the suspect culprit's van from the rural area I live in comes back home I'm sure his *** will be switching the relay. Can you believe :screaming: how stupid crack heads are! One other van in the friggin area besides his and he choses mine. Sorry for venting guys n gals but reality really bites today, especially when I picked him up hitchhiking this morning. LOL.....

Thanks webcat for the fedback. My gem is a 95 CSI and I'm not having any luck with the schematics in my resource pile.webcat said:I looked at the schematics that i have for 1995 and there was no pink orange blue green wired relay , the schematics i have is for 1995 TBI systems , what do you have?
would'nt hurt to put a relay on there , ussually the relays are all the same , for example if you went to pick n pull and got a fuel pump relay it would probally work there too , just make sure you visually inspect it first to make sure its correct
The wires are pnk/blck stripe,
drk blue/white stripe,
light green/blck stripe,
solid black and solid orange.
Will have a look n try at a few other relays I have lying around. Thanks again dude!
Well after digging deeper I discovered that the connector is Oval shaped, not square as the relay normally is. So now that all this attention is directed to this mystery connection I did get the van to fire up with lots of cranking, she's all warmed up and moved it across the yard with same issues after changing VSS Buffer/DRAC. No speedo, brakes lock real hard throwing you forward at any speed, (creeping or moving), and No Trans. Shifting. Oh yes to add to the events, the fuel pump is constantly running. I would guess she surely is trying to Limp Mode home and if it don't change soon it will limp to another home. God hates a quitter but a Jokes a Joke. LOL!! Guess that's the price we pay for buying dirt cheap DOA, surely wish it didn't come with all the baggage and perhaps if it were already painted Yellow, could be another story.
Well since raising everyone's eyebrows I may as well let you know that this missing relay is a "Brake/Shift Interlock Relay". Replaced this bugger with one from Wrecker and the Van is running with Speedometer, Anti-lock Brakes, Transmission (kinda) shifting , and Instrument Cluster lights all working.Beyond Hope said:Thanks webcat for the fedback.

WOO-HOO! :banana:
Need to sort out why no shift into second gear but, drive and OD work well. Will drop thetranny fluid and filter and throw inn some lucas and maybe it will free something up.
This van sat for many years abandoned by others that tried to make it run but just weren't "old school hard headed stubborn enough" to make it run down the road. Need to transfer some plates and insurance next day or two and see what else comes up.
Truly satisfying feeling coming inside with something accomplished today. LOL :layrubber:
LOL, thanks Mr Bowtie for the kind words, kinda was a drawn out saga that brought her closer to my heart. But then again I have Guns n Roses song playing in my head every time I get close to her. "Used to love her but had to kill her"....... LMAO
Hey Moneymaker thanks for the tip. "So far" the van starts on the turn of the key and runs real smooth. Oil pressure appears good from start and maintains @ 275+ kpa(?) all the way through to running Hot. I'm thinking this ghosts are outa the machine now. LOL, will run it a few days after changing out trans fluid and see WTF comes up next before I sell it.moneymaker said:Is it still taking a lot of cranking before she runs? If so, keep an eye on your oil pressure guage and see if it starts up once oil pressure picks up. If so, check out your fuel pump relay.

The saga rolls on and now have plenty of experience on whats not wrong with the beast. Back to square 1 with the fuel tank. The vans not shifting and anti lock brakes not working due to a bad connection within the tank that was over looked when pump was replaced.
Went through every friggin wire back to tank and was stumped why it wants to run in limp mode. My suspicion came about when watching the gas gauge bounce erratically while buddy shook my wire, LOL! Anyway there was a bad ground that was cleaned and repaired, moved on to tank connection and still no change.
Got Buddy to pound on tank and BINGO, the gauge went nuts. Removed tank again and the wires are all fine with the exception of the 2 going to sending unit are a little corroded and slightly loose on the spade. Tightened the smaller and having troubles with the other. I have 2 options I'm thinking of; replace wires which are handy, or get another complete assembly from wrecker. Now this being said I'm still not convinced my black cloud will lift with simply changing wire. What do you all think about the sending unit being NFG?
Anyone have idea's on testing the sending unit while powered up sitting in fuel, preferably not the tank so one can see whats happening? What about the fuel lines, should they be immersed in fuel too?
Thanks for the interests and tips on testing the sending unit.astro355 said:So the van is not shifting at all? Or just under certain conditions?Beyond Hope said:The vans not shifting and anti lock brakes not working due to a bad connection within the tank that was over looked when pump was replaced.
Is one or both of the brake idiot lights lit?
Astro355, the van shifts from first to drive when i take the revs up quite high. its kinda of hard to tell due to my test drive road being the Trans Can Hwy. Way to much traffic to play in, LOL! No brake lights come on when shit happens with my fuel gauge. Going to drop the fluids in tranny and swap out filter hoping this will clean up the shifting.
ray:But the suspicion of the pump sending unit is getting me going that way because how the gauge bounces erratically while driving, I stop and listen to see if the pump is running continuously and yes it is. This being said the puter goes to limp/safe mode and keeps me running off the oil pump. I'm just not convinced enough to keep spending money i don't have on this nightmare, so trying a used complete pump assembly is my best alternative at this time. Thanks again for the support guys!
Hey Guys my apology for not keeping up with this post. This friggin van has been driving me nuts and need to leave alone for lengthy periods to keep the blood pressure down. LOL!Astroplane said:Are you saying the trans starts off in 1st (low) and increases in RPM like normal, but misses 2nd and shifts to 3rd?Beyond Hope said:the van shifts from first to drive when i take the revs up quite high.
Yes Astroplane the van the van starts in First then as I accelerate it will rev quite high, (No Tach) and "sometimes" shift to another gear I'm Assuming is Drive(3rd) due to lag. My problem is I even flutter the gas pedal to get it ti shift. As mentioned earlier all fluids been drained and new filter since last post and it was grossly contaminated with GRAVEL. My guess is the trans is pooched! Someone left me a Ghost alright. I'm going to throw some plates on a drive down the highway for awhile and reset the puter. Not getting codes to mention, just in denial of NFG trans. LOL!
I'm really confused on how this misunderstanding I have been reading on all my data and electrical diagrams, How I was expecting that Fuel pump "shuts down" after the key goes to run for 2-3 secs. Thanks for the heads up and getting me off an issue other than my own. Sure wish I was on top of that, been soooooooooo many hours lost trying to fix something that wasn't broken. :shrug:
Thanks 94Van Guy for the feedback. Yes these words are only used as experiences and usually we all eventually learn.
