92 4runner v6 4wd engine cranks wont start

[ninja309]

My 92 4runner v6 4wd engine cranks but no start. Have replaced all electrics, new ignition, distributor, etc. Have checked timing belt settings, and replaced all sensors except the crank shaft sensor (or oil switch? Manual is crap at defining). Now what do I do?

Seems like mine is same. '95 3.0 4runner. Have spark and fuel pressure. Have double checked timing. Have even tried priming via the cold start injector. Does not fire at all.

Check your air filter, maybe it's clogged? Also check your fuel filter. Look for the simple solutions, air, fuel, spark. You replaced all spark related items it sounds like, so now look towards your air and fuel.

Well, I'm in a very similar boat as you with our 1990 4runner. Cranks with loads of spark but no fuel. Since it has broken down in the islands, I'm replacing the following next week:
-fuel pump and screen
-efi relay
-fuel pressure regulator
When I head up to repair it, I'll bring up the factory manual set, multimeter, and tools with a report back. I suspect our fuel pump is shot, but there could also be an electrical element to this issues as well. As the others have said, you might check for fuel and spark first. Best of luck with it.

Heres an old school tip for the electric fuel pump

Make sure key is in ignition and turned to on

Find the lid of the fuel pump

hold a screwdriver, metal side touching the lid

put your ear up to it. humming? its working!!!!
