I have a 92 B2200 EFI (California truck). Turns over, fires, runs for a second then dies.Good Spark, good fuel delivery to the rail. Have replaced distributor cap, rotor, wires, plugs, fuel filter, fuel pressure regulator and what I think was a control module (1" square unit on fender, drivers side). I have it boiled down to the camshaft sensor- what do you guys think? And if so- can I just replace it or do I have to replace the entire distributor? Looks like I have to replace the whole thing. I'm out of options, and out of money and need to get to work! Thanks for any help you might give!

 

Over 70 people have looked at my problem and NO One has replied!! I REALLY NEED HELP! I AM STUMPED!!! I have, in addition to the work above, now purchased a new distributor and the reaction is the same... It starts, runs for a second, then dies. So the cam sensor is not the culprit.. I KNOW IT IS A FUEL DELIVERY PROBLEM!!
My new question: is there some gadget or sensor somewhere that has the power to shut off the fuel if it senses something is wrong (ie; low oil, crash, etc.). I know most modern cars have that feature. Could this be what is faulty and is shutting off my fuel after intial fire up? PLEASE HELP ME! I need to get to work in the AM!
