Was driving truck home it suddenly stopped and would not start had it towed to mechanic had crankposition sensor replaced cam position senor replaced had computer checked and replaced vehicle will turn over but not firing to injectors or coil something has shut it completley down
It should have two relays that control power to the engine/ecm and the fuel pump. One of them probably failed.
SOURCE: 1992 dodge 318 engine turns over, but no start. No
if truck has a ceramic ballist resistor near and connected to coil this could be problem or the crk posistion sensor could be too, i would change ballast first if you have on your truck appx cost $10

Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Then i think i'd be dumping some soapy water on the intake gaskets checking for leaks. ANd wiggle the **** out of all vacuum hoses. ( you probably did that) And if there aren't any, your cam could be tired. You got a tough one there. Hard to figure with a keyboard.

The injectors are mainly controlled by the good output of an auto shut-down relay which is directly affected by the fuel pump relay straight from the PCM.The easiest way to check the fuel pump relay is turn on the key,wait a minute,and see if the fuel guage comes up to proper level,helps if you know fairly close how much gas you do have.A couple other things which could cause intermittent cranking are the ignition switch may be going bad,or a bad connection in the ignition wire harness but the ignition itself is way more common.Also a near dead battery.The lights will sometimes appear somewhat bright but to start requires lots and lots of power.A good battery should read near 13V.A bad one will read around 11.8,11.9V and could cause intermittent crank.A crank position sensor could cause it,but for the most part,if a sensor is bad the system either works or it does not.That's about all except do you have intermittent start or no start whatsoever,even jumpers?If this doesn't work or you need more help,just comment here and I will get an autolink to your post and reply ASAP.Good luck!
