Just thought I'd drop an info post for everyone.

My 1990 Trooper, 4cyl fuel injection, just started refusing to start.

I went through a lot of unnecessary steps because I didn't check the
fuel pressure first. I did remove the fuel line and cranked the engine,
and because fuel came out of the line I didn't bother to actually
pressure test it.

After going in to check the timing belt/ ignition timing, distributor,
etc. I finally did check the pressure and sure enough is was only a few
pounds.

Anyway, if your trooper goes from running to nothing in 1 morning flat,
using the fuel pressure gauge may just save you quite a bit of
aggravation.

Had it towed to Pep Boys since I had no pressure gauge and assumed it
couldn't be the fuel pump. The rest of my procedure was to eat chips
and soda while I waited to hear from them it was the fuel pump I had
been so sure wasn't broke.

All in all, $400 for towing, labor, parts and taxes. FYI it was the
original 16 year old pump.

I just wish I had bought a fuel pressure gauge myself instead of paying
for diagnostic and towing. By the time I had paid for that, it wasn't
worth doing it as a shade tree project.

Anyway, good luck, hope this spare someone else some time and money
when playing with their trooper.
