I am new to this and looking for help. Ihave a 97 ranger with 2.3. my son rearended a tahoe and the air bag deployed. i got the body repaired but when i tried to start it it will not idle. replaced the IAC, MAF, EVR. the fuel pressure is 35-40 psi when running and does not leak down after the engine dies. the engine starts and runs for a few seconds then dies. i can keep it running by feathering the throttle. any ideas
 
My neighbor owns a 96 Supercab V6 3.0. He once had a very similar problem.

In his case, it was a plastic tube which runs from the air intake hose (between the air filter and the throtle body) to somewhere under the engine. That plastic tube was broken and loose and his truck had exactly the same symptom as your truck. I think its a vacum line.

He reatached that hose and glued it to the air intake and the problem was gone.

Maybe in the accident your son had that hose either broke or snaped off.

Good luck
 
Engine will not run

First check for any codes. My long distant guesses are air idle sensor or crank position sensor or there is a vacuum leak in the intake manifold parts. Changing the gaskets is time consuming and about $15 in gaskets. All the vacuum hoses and connections can be quickly checked with some WD40 or some start fluid. frank
