Does any one have any ideas?

1993 toyota pick up 22re having really intermittent broblem in the ignition circuit.Somethimee i'd be cranking all day,and the darn thing dosent start.Then in the morning ,I'd start it with one touch.
I have changed the plug wires, the distributer cap, and the plugs are all firing.At first I thought my problem was the igniter pack but i'm still not sure.Please help :banghead:

How about looking at the starter igniter.Well maybe i dont know for sure.Not enough information.
Sorry if i am wrong.I know nothing about my truck.
But hey good luck to you !

Are you getting fuel to the engine?

You mentioned the plugs are all firing, if you are certain that you have good spark when cranking it, try hitting it with starting fluid next time it won't start. If it starts with the fluid, check to see if your fuel pressure is bleeding off after you turn the truck off. It may be a bad fuel pressure accumulator

is the outside temp the same when it starts and when it doesn't? Maybe the cold start injector or the temp sensor is inop?

It appears that the truck is no longer giving the problem. I just cant understand how because it was really a pain. it fixed on its own."beats Me"

check and clean and grease all wiring plugs underhood and at fuel tank and on pass side in the cab along the rocker under the carpeting(the fuel pump wire is in this and the connector is a real corrosion issue, i snipped mine off and crimped all the wires back together on mine)


corrosion in wiring plugs is a real problem on these trucks

very common

good luck

When the problem is present and you crank does the tachometer (RPM gauge) needle jump up and down? it's supposed to if not yu have a coil related problem, usually the coils fail when they are underload like climbing a steep hill or acceletating hard.

About half of the ECU codes stored on the first & second generation EFI Toyotas don't show a constant blinking check engine light therefore you must pull the ECU codes to see if a fault is registered.

To pull the ECU codes:

All 1980-1995 and including 1995 EFI equipped vehicle allow you to find engine and related faults by pulling the ECU (computer) codes without the need for a handheld OBDII diagnosis scanner,the sites listed below have the fault codes needed to pull the codes and the instructions on how to do it:

Pulling the ECU codes is the first thing I do to diagnosis a problem thereafter I reset the ECU to see if the same problems show up and if so I then take voltage measurements both with the engine running and not and compare with the factory service manual,I also close the ignition switch after a cold engine and also after a warm engine and compare them with the factory service manual.This technique will completely isolate your problem without having to do trial and error and it is the technique I use when repairing tv's,vcr's,home/car audio.

Any Public Library in your area would have the Factory service manual,Haynes,Chiltons,Mitchells,Clymers,Bentley and Toyota repair books.

There is also free AutoZone service manuals at:

1)buy a used one off e-bay
2)some Toyota dealerships may give you one or sell it for $10-20 (used) as most Toyota dealerships don't repair many old Toyotas and no longer need the service manual
3)some public libraries sell their old books as they are not in demand any longer
4)some free buy & sell classified papers,websites and bulletin boards may have some used ones for sale
5)some junk yards may have one laying around
6)some Toyota specialty garages may have one laying around and no longer use it as the vehicle may be too old and those mechanics probably have so much experience that they could publish their own factory service manual with corrections and "real world repair tips"
7)if someone has the FSM maybe they could scan all of the pages and post it on a site for all of us to download or view.
