if you read my post about 1 week ago i was talking about having fuel line problems with it leaking and i need to get some washers to stop it from doing so. well i get the washers. when i was working on it the week before i was getting spark and i was getting fuel. id turn it to two on the ignition and fuel would start to poor out which i was happy that i was even getting fuel. well i come back today and start working on the car after i get my washers. i start putting the washers on tighten everything down and in high hopes of it starting, i get nothing. i take off the fuel line again and see if i can get any fuel to come out. nothing. i check to now see if i have spark. nothing. what the hell. when i left it last sat. i had both spark and fuel, and now that im back im not getting anything. anyone have a theory on what might be going on. argh..

mid day bump

 

Fuel and spark? Hmm, are you getting a cel? Have you checked fuses? You can't hear the fuel pump prime?

Off hand, I'm thinking main relay b/c it can cut fuel and spark.

 

Is your ECU plugged in? Not to be a dick or anything just something to check I've done that a few times.

 

well since my car is obd1 blown90hatchs harness has a toggle switch that can be set to on to check your codes. ive got the sitch hooked to the ecu and a ground and wether the switch is on or off my engine light stays on constantly. i checked the small fuses both under the hood and inside the car. all good. as for the larger fuses in the fuse box i haven't yet. i wasn't sure on how to test them. do i just unscrew them or can you just unplug them like any other fuse, i wasn't too sure so i didn't play around with them. i can hear a buzz which i believe is the fuel pump trying to prime (i think thats the noise im hearing) but the weird thing is is that it made the same noise when i got fuel and now its making the exact same noise and im not getting any fuel. also what and where is the main relay and how can i check it. the car is gutted so i can check anything that would be under the dash pretty easily so keep the info coming.

as for the ecu, i did make sure it was still plugged in and it seemed to be the same as it was i left it when i was getting all the fuel etc. i was thinking about unplugging it for about 10 min and then try hooking it back up. but i didn't know if that would work or not. and i definately wont consider anyone a dick, im open to all suggestions to help me get this car running.

thanks for everyones help so far. keep it coming.

 

Yes you can unscrew the fuses under the hood check those to make sure nothing is blown. if all is well try resetting your ecu by pulling the hazard fuse for 10 sec. with the keys out of the ignition put it back, then see what you get.

 

check your grounds.

 

i don't believe i have a thermo housing ground could i attach one here?

the little screw hole right above the brown plug? could that be a possible place to set the ground? also could this have some effect on why im not getting spark etc. im going to make some good grounds tomorrow and check the rest of the fuses. hopefully ill stumble on something

 

morning bump.

 

Isn't a solid on indicate an ECU failure? I know it does on an ODB0

 

you need that thermostat ground!!!

I believe either that, or when it throws a code that doesn't exist.

 

okay, i redid my grounds. i now have valve cover ground, tranny ground, and thermo ground. they are made of 4g wire and gold terminals, so i would consider them decent. should i make any more grounds to be safe. (alternator, starter, thats if you can ground those. i wasn't sure)

i wired up my thermo sensor so now thats hooked up. it wasn't before.

weird thing about after hooking the thermo sensor up was that it seemed like if my keys were in the ignition it would beep to alert me that they were left there. now after hooking up these grounds and thermo sensor it doesn't do that anymore unless i put the key at one. maybe i just imagined that.

i have also checked all fuses. which fuse is the ecu fuse. i have 3 large fuses and im pretty sure that one is to the battery and the other two are to the wire harness. i wasn't sure which one was the ecu though. all fuses were good.

as of now im still not getting spark or fuel. the weird thing is i was using one of the power light tools to see if i had any power going through any of the wires(looks like a screw driver with a light in it) and when i touched any of the metal prongs coming from the wireharness side of the distributor, fuel would shoot out of the fuel line. does this mean anything? i just thought it odd cause it doesn't shoot fuel when the wire harness is plugged into the distributor.

i also unplugged the ecu for about 10 min and tried to reset it. after i did that it didn't seem like the fuel pump wanted to prime so i left it alone for a few minutes and tried it again and i heard the pump trying to prime again, but no fuel still.

anyone know what some of my problems might be?

 

Do you have gas in the tank? Just want to make sure.

 

yes i have about 1/4th of a tank left of probably 88 octane. the low crap. just wanted to get it started then take it and get some higher octane once i got it running.

 

 

 

Good post. These little trouble shooting issues are the worst eva. Are you sure that the fuel pump is priming? Loosen the fuel line where it goes into the rail. Does fuel leak out? Clean your plugs off. Remove the plug wires to insure no spark....lol even though I know you arent getting any...turn the car over many times. Check your plugs. Are they soaked in gas?

Do you know how to read pinouts on the ecu harness? Did you change fuel pumps? Sorry for all the questions.

Main relay!!!

 

hey i love the questions, helps narrow it down as for the pinouts for the ecu i believe i can. thats if you mean the a1 a2 etc. as for the fuel pump i did not change it. heck, i can't even get fuel to just simply come out of it except when i trip the distributor, fuel will pour out for a slight second then stop again. im pretty sure they aren't soaked in gas (the plugs) cause i can't even get fuel to the engine. ill also give a good cleaning to the plugs.

how do i check the main relay and where is that darned thing.

also what i think is the fuel pump priming is when i set the car to on i get a battery light, check engine light, seat belt light, and a couple others but as those lights are lit i hear this buzz. its very slight and its hard to tell where its coming from. thanks for all the help

bump for this guy

 

haha thanks man. appreciate it!

 

Lay behind the car near the gas tank. Have someone turn the key to the on position II. Listen for the 3 second or so fuel prime. The main relay is located above the hood release to the left of the fuse box on an EF. Get a Helms manual for your car if you can kick the $$$.....if not, get a cheap Haynes from an autoparts store. It has all the steps in it to check your main relay. Check your PM too.

the main relay is located right above the hood latch its a little black relay about 2"x2" in size you might have to remove that little change droor , they are like $30 auto store.
