82 crossfire wont start
i did searches for old post but did not solve problem.
here's the situation. Havent started the vette in approx 3 months. went to start it up battery dead. charged it up and it cranks, it would run for about 1-3 seconds and would die. i tried getting it to run for about 5 min. without success. I could see the injectors pump fuel but engine would die as mentioned. My fuel gauge was low so i thought maybe its out of gas. put about 3 galls into it but no change.(They car is on a slight sloped driveway approx20degrees i dont think that would make any difference would it?) But i noticed that the injectors no longer were spraying fuel as they were. So i checked the fuses for the fuel pump, the injectors, and "crank". none were blown. I sprayed starting fluid and it runs for about second and dies. I did a quick check on my fuel filter i disconnected it and could see no obvious clog,for kicks I blew into it and felt air coming out the other side. I also looked at the electrical connection to the TBs and the were on and not corroded (as they were working) but i wanted to make sure.
Any ideas??? im confused
any help is truly appreciated thanks

Have you tried the crossfire vault site - loads of very experienced crossfire specific guys on there that will probably be able to help

If its electronic component related you would get a check engine light. Do you? Any codes?
Could be a lot of things. Do this let me know what you hear/see. Turn the key to on...do you hear the pump in the tank turn on for 2 seconds? Do you hear the injectors kick in a prime the system...once again a short burst identified by sound...you will hear the injectors. When you turn the key does the oil pressure on the guage climb? Pop the hood and remove the filter.When it finally does start do you see spray from the injectors. When it dies are the injectors still spraying or do the injectors stop spraying and then it dies.

Sounds like an old olds we re built did everything put it all back together no gas . guy said we needed to prime our injection system????
Fuel pump? fuel filter? My buddy next door has an 85 its a hard startin and running car he revvvs it up till it runs better and away he goes .

Aren't the injectors supposed to purge themselves of air?

If you turn the ign. on the system pressurizes and the injectors fire a couple times, that will purge any air and you should have immediate fuel pressure.
Put more gas in the tank and try again, the fuel also lubricates and cools the fuel pump so you may have killed it.

ok guys i tried again this morning, well the injectors are firing again, wooo, but it is still turning off after about 1 second, i watched the injectors and they are still firing when the cars dies. I do not hear the pump priming but ill try listening again , initially it did prime the system. my check engine light does come on but i dont know if there are any codes (dont have the equipment). I also looked and i do have oil pressure (because i read in an old thread that if you had no pressure engine wouldnt run). What do you think?

Try resetting the computer again. Disconnect the battery, turn the key to the start position, and hold it there for thirty seconds. Release the key, remove it, connect the battery, and try starting again.

You can check for codes with a paper clip. Get one bend it in a "U" shape. Remove your ashtray...see the plug below it? Short the two pins furthest to the driverside with the paper clip. Ignition on. The check engine lite will flash code 12 three times. What you see is a short flash for 1 followed by a pause and two quicker flashes for 2...this means 12. After it flashes 12 three times the codes spit out. Example code 43 will be four fast flashes followed by a short pause then 3 fast flashes. When it its done spitting out the codes it will flash 12 three more times to tell you it is done. Try it. Post the codes....I'll look them up.
It does not sound fuel delivery related...injectors are still spitting out gas when it stalls. Those codes will tell you what it is.

are the injectors actually squirting fuel or do you just hear them ticking??? Check this, if they are ticking but not squirting a proper fuel spray the pump may be cutting out. It may be the oil pressure sender, allowing you to start the car on the relay but when the sender has to take over (when oil press is adequate) it will crap out.

So the oil pressure sender will cause the motor to shut off even if oil pressure is fine. Makes sense to me.

ok so i checked for codes it just flashes 12 (one followed by two flashes).I reset the computer, tried again and checked for codes but still just 12. I changed out all the spark plugs and fuel filter, but still doing the same thing. I checked the injectors and they are spitting fuel when it dies. I also checked and my oil pressure gauge is still reading good pressure when it starts and then drops once the car dies. someone mentioned a ignition coil ??? do you guys think that may be it? thats the part on top of the distributor right? also i read on crossfore vault that ignition modulesometimes goes bad,where is that?what does it look like?

The ignition module is inside the distributor, and very easy to replace. Pull the cap, and the rotor. THe module is mounted on the base plate held on with 2 screws. Remove the screws, gently remove the wires from both ends of the module, put heat sink compund on the bottom of the new module and reinstall. Since it does start,I would not suspect the module but I'd take a close look at the rotor. I've seen the HEI's burn a tiny hole right thru the rotor under the metal tab in the center. Coil is the same- very easy to replace- 2 screws on top of the distributor, remove the cover and there it is.
Durango- the fuel pump relay is no trick- if I recall, it's mounted on the firewall.

So would that mean ignition coil is the problem or ignition module?

I would also check all the wires coming from the distributor...not likely the probelm because is starts sometimes and stalls sometimes.
