Ok, so I bought it for $400 and now into it for about $900, When its cold it wont start just turns over. Will fire with starting fluid or jumped from another car and run great but shut it down and wait 20min it wont fire again without some help. Replaced spider injector, plugs wires, ignition coil, battery, fuel filter, drained tank and filled with new gas. Im getting the right voltage to the coil. Im just baffled and dont know what else to do.

When you changed the spider injector did you pressurize the pump with the plenum still open to check for any leaks? I just went through changing my fuel pressure regulator and return fuel lines inside the plenum thats why I ask. Luck for me the spider injector wasn't leaking....YET!!

You have the symptoms of not enough fuel for startup, which usually points at the pump.

Get a fuel injection tester from Harbor Freight for ~$14 and screw it onto the schrader valve at the back of the intake on the driver's side. You need 62-64 psi for cold start, 60-66 psi is the spec. And it should hold the pressure for at least 10 minutes.

 

[adamt860]

I did that, its saying 48-49psi when I turn the key to on, when cranked it jumps to about 62psi.

 

[Leeann_93]

Spec is KOEO (key on engine off) 60-66 psi, 62-64 psi for cold start.

Your pump isn't putting out enough pressure to start.

Thanks guys, looks like im dropping the tank sunday.

I concur, sounds just like Grumpy before the fuel pump rebuild.

Fuel pump a no go, replacing ignition module in the morning. Turning into the money pit, but cant wait till its perfect. Also replaced the coolant temp sensor and nothing. Something about these vans, usaully it would have had a for sale sign on it already. I hate electrical problems :screaming:

 

[Mr_Bowtie]

Don't you guys/gals think maybe his fuel pressure regulator could be causing the problem? Just not holding enough pressure in the line & allowing the fuel to just go back to the tank. Which would cause the low pressure reading. He did change that just the spider injection.

 

[Leeann_93]

The spider comes with the FPR installed.

That's not to say it isn't bad out of the box, but the issue predates the spider replacement.

 

[adamt860]

Its running and running great. :chevy:

 

[Leeann_93]

Good!

What got it fixed?
