I've had the ECM checked, good fuel pressure, good coil. The injectors aren't working. If fuel "leaks" past into the cylinders it will run momentarily. Is there a relay or a cam sensor that can be checked or changed?

First, welcome to the site.

It (hopefully) would help us help you if we knew which engine you have, i.e., 4 or 6 cylinder.

Also, any history leading up to the current condition.

The description make it sound like the 2.8. As leakage on the other engines is a bit difficult to observe.

If it is the 2.8 and it is a Trooper, do the 4-way flashers work? If not replace the module. No kidding, there is some strange bit of wiring in there that affects the injectors. The engine will run with fuel poured down the throat of the TB, but there is zero fuel from the injectors.

There is also a chance of it being bad/clogged injectors. If that is the case, I think replacement is the best option. Jim or Ed have a link for cheap replacements.

Good Luck,
Michael

let me know if you need 2.6 injectors... i may have some used replacement lying around.
