Did you verify the timing marks on all the crucial points, to assure you didn't slip a tooth on the belt? Did you make sure the distributor is in the right position?
Fixed it. Although I had spark, I threw in new plugs and it started up. I really thought the ecu was the problem, since it seemed to just die without much drama or reason; no stuttering or misfiring or anything...but hey I'm glad it's fixed. Now to fix the engine ticking. Not sure if it's a sticking lifter, bent push rod, worn rocker arm, or weak valve spring but it comes and goes with the pressure and viscosity of the oil. Any tips?
Again, with no engine specified, it's difficult to give a difinitive answer. However, if it's original to your truck, it doesn't HAVE push rods, so we can eliminate that one.
If it's a 2.0 it could be an adjustment. If it's a 2.4, likely the lifters (located inside the rocker arms) are worn. A little Mystery Oil will help temporarily. A good oil flush and change might help, too. Though controversial on this website, I recommend a few ounces of Sea Foam in the crank case before the oil change, and drive it a few miles. Drain the oil as soon as the engine stops. That way ALL the gunkus~funkus can drain out. (Letting the engine cool down allows crap to settle and possibly not drain out).
fuel pressure reg? gas in the vacuum line? Let me know if you fixed it yet. I'm having the same problem,
Instakill diagnosed the fault as a dead ICM in the distributor (ignition control module). ECU wasn't getting injector/ignition pulse signal. He opted to replace the whole distributor assembly which rectified the issue (didn't state if it was a new or used part...)
