After cranking the engine over without firing- pull a spark plug out to see if it is dry-that would indicate that your not getting fuel into the combustion chamber or if it is wet with gas you may not be getting spark-cheers Denny
Testimonial: "Thanks Danny we are getting spark and it even fires sometimes. It just won't start without spraying engine start and then it goes...while you keep spraying it runs but as soon as you stop so does the car..fuel pump relay ect has been check I think I'm going without food and getting a mechanic...my son can take things off and replace stuff but he isnt a mechanic and we dont really know what to do know...Im thinking a cliff and tossing it off..lol...thank you for trying to help"

i was once pulling a trailer with a ranger when it suddenly lost power and the engine died. turns out the problem was with the fuel shut off inertia switch. the switch is supposed to activate in case of accident. on my model the inertia switch is located in the passenger side under the glove box. dont know where yours is located. once you find it, just push the button and see if it resets. good luck.

Please go to the crossfire injection forum to get some straight answers to the 82 corvette CFI system and how to troubleshoot it properly. There's a lot of misinformation given here, so much so, I don't know where to begin.
One thing is, the 82 corvette CFI does NOT have a MassAir Flow sensor system, it uses MAP and O2 mostly. The CTS sends a signal to the ECM telling it what the temp of the motor is and in turn the ECM controls the amount of fuel being dumped. On the older (orignal) CTS sensors, they have one wire and takes its ground from the threads. If any coorosion takes place, usually the CTS will report a cold engine and request lots of fuel.
To repair this issue, install one of the newer style CTS sensors that have two wires, one for signal and the other is ground.
Fuel pressure and vacuum leaks on any CFI motor play key roles. Set the FP to 14-15psi measured inbetween the TBs. The regulator is located on the rear TB and must be slightly moded to make it adjustable and can be done in a few minutes.
SOURCE: 1991 Olds Cutlass Ciera 3.3 v6 would start, run a
jrtvett's "unplug one injector and start" troubleshooting procedure would work if one injector is bad. If more than one injector is bad, then not so sure.
Like you mentioned, one or more injector(s) can go bad and it causes the others to stop working as well. After our experience, I am convinced this observation (fault mode) is correct (see below). Its as if upon warmup the solenoid in the faulty injector shorts, resulting in short circuit of signals to all the other injectors.
We have a 1989 Olds Cutlass Ciera with the 2.8L V6 that recently had the same fault: At least one injector went bad after warmup, then engine refused to restart. All other possibilities were eliminated, including crank shaft sensor, ECM, ignition pack, idle start valve, bad gas, rail pressure, etc.
No Service Engine light illuminated, and there were no fault codes in the ECM computer.
The jrtvett procedure could not easily be utilized in our case because all the injector connectors are underneath the intake manifold and inaccessible.
My cousin is a Ford mechanic told me of an analysis procedure Ford uses to troubleshoot injector problems. They display rail pressure on a LCD or CRT monitor and can see pressure drop with each injector's opening. Unfortunately, if the car is not starting, then this test will not be of much use. The engine has to be idling or at least all of the solenoids in all of the injectors operational to use this test. If engine won't start, then its clear none of the injectors are opening as described above, then no fluctuations in rail pressure would be displayed.
The shop that was working on our car decided to replaced all of the injectors, and the engine now runs like new.
Due to inaccessibility of injectors and fact these injectors were inexpensive ($40-$50 each), it was wise just to replace all six. Grading old injectors is not exact science.
