I have a 91 Toyota pick up it was running fine I killed it now it will not start it is not firing and I don't think the fuel pump is pumping
Ok , (killed?)
there are 6 spark plugs, it will take all 6 firing to run
are all 6 sparking, called a spark test.
BTW1, the ECU will not inject fuel if it even suspects spark is bad.
it has 3 monitors for spark, if one dies, fuel is cut and in many case
the fuel pump too, all cars. (fire safety)
so SPARK is first.
ever do a 60,000 mile tune up in the last decade?
if not , maybe now is that magic moment?
fuel can burn weak or no spark.
the 60k also nets you a new fuel filter .
check spark directly at the the coil too....not just the 6 spark wires.
if the coil sparks and not the 6 that means the cam belt slipped.
(hard to believe a chain can but see 2 like that, owner was deaf)
if you have spark, then test fuel works
spary it in now.
verrrommmmmmmm stall.
?
that means the fuel pressure is low.
if you get this far,the rest is easy, ask.

to check the fuel pump on you car you need to put ignition in the on position and open the butterfly of the MAF sensor that is mounted on top of your air filter. Toyota's fuel filter won't come on unless there is air going in the engine. your problem may not be the pump, so you need to check the pump properly.

Fuel pump relay is in the engine compartment left side fuse block

SOURCE: toy turns over but wont run change fuel filter n fuel pump still
The fuel pump should run for a second or two when you first turn the key on, but then shuts down to prevent the engine from flooding if the computer does not get a signal from the crank or cam sensors which the computer uses to trigger the ignition system. So no spark no fuel. Check to see if you have a spark in the ignition system.

I'm willing to bet you have bad fuel injectors. Back in 91 they had a problem with on injector shorting out causing the rest to short out. I have a 91 that had the same problem, and my injectors were junk.
