My 93 SE suddenly stopped starting some time ago. I've replaced some things and now have a video to show the behavior rather than describing it.

The plugs are dirty but not 'fouled' per say -- I had some leak-down from the valve cover gaskets that may have gotten in to the engine.

I replaced the starter, battery, and battery terminals recently which took care of a host of other issues. I also cleaned the PCV valve, replaced spark plugs, air filter, fuel filter.

I've also tested these with no symptoms: compression test, electrical test on all ignition coils (ohm and spark), MAF, throttle position sensor. The ECU throws no codes.

Any help tracking down the cause is appreciated.

Check the fuel pressure next.

**edit ,i must have mis-read that as trouble getting start signal etc.
so nevermind

could it be your ignition switch?i have a spare one we could just plug in to test it by unplugging yours without removing your ignition switch . mine is from a 92 se 5mt, im in north seattle

try fuel pump relay and fuel pump. pull the back seat and check the fuel pump harness as well and look for corrosion (had a similar problem like that).

also check the ecu for any codes.

The ground on the FP sending unit is a known issue for no start condition. If the plastic insulation on the top of the sending unit cover is cracked or damaged this could cause a no start condition.

[quote=shiloh51933;8686788]Interesting -- when you say "sending unit" you mean the connectors to the pump under the rear seat or something else?

I think he means the pump assembly itself. The actual sending unit doesn't do anything that would prevent the car from starting.

My fuel pump harness had actually corroded and caused a no-start condition.

Fuel pressure read at nearly 0PSI so the pump is the culprit. Harness/etc. was fine.
