Postby breeze9 [OP] » January 20th 2011, 2:23pm

I have a 94 Safari that was brought to me needing a steering column. I know only the 93-95 AWD is the only one that will work. After the install I get crank but no start. Have great fuel pressure. Checked and had spark from coil but not plugs. The module tested bad so I changed it.Still have the same problem. As far as I can tell everything is hooked up correctly. Anyone have a clue where to start looking?

Make sure all connections are secure , unseat and re-seat , check every fuse in both interior fuse boxes under dash and under hood ,ENG ING , ECMB etc. owners manual will tell you which fuses do what , check the crankshaft sensor and connections , camshaft position sensor connections and PCM connections , distributor cap and rotor may have corrosion or worn out , there is also a fusible link in the starting circuit and you may have dislodged a connector during the steering column removal /installation

Having spark usually indicates a good module. Was it a continuous stream while cranking, or just one spark when the ignition was turned on/off? If the coil is putting out a steady stream then your problem exists between the coil wire and the spark plug(s). If there's no spark at any of the plugs, I'd look to the coil wire, distributor cap, and or rotor. Are the plugs new? Were they ever flooded? I once ruined a set of new plugs in less than 15 minutes in an engine that flooded them badly.

If you're going to be replacing parts it's reported that an OEM cap & rotor will give the best service.

plugs wires cap and rotor are new. I had spark from the coil but not to the plugs. The module was bad and after I replaced it I have the same trouble. Good spark from the coil to cap but nothing to the plugs. Rechecked all connections and see nothing left out.

There was someone about a month ago that had the same problem and they changed the module because it tested bad and then they changed the crank sensor and that solved their problem , if the crank sensor is bad or weak you will not get it started ,,something to check as it is only a magnet and they do go bad , if you have a meter trace voltages and ohms levels and compare to what they should be
Good luck to ya

Is the rotor making contact with the button in the cap? You should see a swirly mark or two in the center of the rotor contact by now.

Not sure what you mean by that , as with electrical connections the connecting points inside the connectors cannot be seen when the connectors are put together . sometimes corrosion builds up on the metal contacts and creates a high enough electrical resistance to prevent passing sufficient voltage , and by merely removing the plug connector making sure the contacts are clean and putting it back on fixes the problem . on a 94 ; not sure if you have a crank sensor like the Gen 2 has

take the cap off and twist the rotor, you shouldn't be able to. you might have a bad distributor. If you are getting spark from the coil, then you have a spark distribution problem. If none of the spark plug wires are lighting up, then the distributor either isn't spinning, or you have a bad contact between the cap and the rotor.
A temporary fix usually becomes a permanent solution, therefore it does not exist.

Sorry what I meant was the rotor is moving and the plugs are not sparking. I have good spark to the cap but nothing at the wires. Could something be shorting out the module? The connectors for the column all line up other than the one for the wiper. Could this have something to do with the auto start and key-less entry?

Keyless entry is the door locks , if you have auto-start as in remote start then you have an aftermarket system that could be causing the problem ,,,Hope you put some dielectric grease under that module cause if you don't it will overheat ,burn out and then you will have to replace it as it won't start with a bad module, yea you should should make sure everything lines up well
