94 GSR turns over but wont start!

[Grnblur]

Ive got a 94 gsr w/ a 2000 gsr motor everything was fine it started up and ran for a while a few days ago and now it turns over all day but wont start. I have checked the fuel pump and replaced the fuel filter but no luck.

[Red_EJ1]

Even though you replaced the pump, Is it kicking on?

[Grnblur]

yea pump kicks on believe me i didnt get the bottom fuelline tightend up good enough and got fuel all over the ground. its still the old pump but new filter i pulled it and the tank and cleaned both out tank was full of rust.

On a '94? Damn. You might want to check for a clogged line then. Like the line to the fuel rail itself.

[Grnblur]

you think it could clog past the filter? its worth a try i guess what about clogged injectors? where are the relays located that have to do with the fuel system?

The main relay you could start with. But it could be the filter itself that's clogged. That's why i recommend checking downpath of the filter.

check spark..

[Red_EJ1]

check spark..
I fgured he would be better off checking fuel first because he mentioned rust being in the gas tank.

Added to list of things to check tomorrow. where abouts can i find the main relay?

Right up under the dash/steering column area. Bigger grey or black box.

1-check for fuel
2-check for spark
3-check compression
4-let us know what ya got....

[Grnblur]

gotcha ill hit it hard tomorrow and let you know what happens appreciate it.

i Checked and have no spark the main relay isnt bad and i checked the distributor and icm and all checks out fine?

[Grnblur]

used a dmm and oil level is good

[Barefoot]

if your dizzy is good and u have oil not sure as far as oil pressure. the only other things i can think of is to check your ecu fuses and your ecu.

if your dizzy is good and u have oil not sure as far as oil pressure. the only other things i can think of is to check your ecu fuses and your ecu. listen to this man ^^^if the dizzy is good .... then its your ecu ... but double check your dizzy . put it on a friends car and see if it will crank it .

[Grnblur]

will the dizzy swap from the gsr to my ls?

[allmotorX]

yea it should^^

[turbob20]

you could also swap the ls to the gsr but youll have to cut one ear to clear the vtec solenoid and can only use top bolt just to check that is. main relay has a big brown plug and is bolted right next to the hood pull. imo the ecu may not be letting injectors pulse but usually fuel pump wont run in this situation too so i dont know. my frriends does this all the time in his del sol cause of a leak that lets water run down the conectors. take ecu panels off top & bottom and blow dry curcuit board even if it doesnt look wet doesnt mean it wasnt. works every time on his car untill his cheap ass replaces rubber or shorts the ecu.lol.

[Grnblur]

it did rain on the car for the first time in a while right before it quit working so thanks. and yea i figured out the hard way that they dont just swap over and i dont feel like cutting my perfectly good ls dizzy to put on the gsr damn vtec lol. ill try the ecu bit first thanks.

If you got no spark its most likely your coil pack in the distributor...

Main relay is working if your fuel pump engages when you turn the key on...

For a car that was running fine and to not run I would tackle the coil pack first.. You can just swap the coil pack from an ls into yours to see if it works. Or if you want to just look at your coil pack take it out and see if it has burn marks on the flat sides. I have seen it many times..

Appreciate it will try tomorrow, man this thing is beginning to kick me in the ass worst idea i ever had. lol learn from your mistakes or just make new ones.

[DeeAOne]

check grounds too! might sound simple but even a little 12mm bolt with a loose ground under it could keep it from starting. happened to me more than once.


:2cents:

[turbob20]

this is true, theres a ground for the harnes on the thermostat housing,check that too! and one from the frame to the tranny...

[Grnblur]

grounds are fine, replaced sparkplugs because someone told me they were fouled out and still nothing swaped icm's and no go so i dont know what else to try.

[turbob20]

try a known good ecu and recheck fuses under hood and in car.is there any anti theft on it? maybe a wire came loose...

[VickNotic]

just a thought but, maybe you should look into your timing as well. And if you have a xtra ignitor replace that out as well and see what it do. I went to a problem like that before, and it was just my ignitor that went out all of a sudden. And as to the no spark, check if everything is lined up right and stuff. possibly timing might have jumped ?? just a thought. happened to me once. 8D

[turbob20]

check to see if timing belts broke!

[j0nbunklah0m]

check ur battery... my car did this and even a jump wouldnt start it.. but then i replaced the battery n it started up fine

[slowinmidga]

my guess would be dizzy or main relay

[Ezac]

check the the rotor button if the screw came loose in it it will turn over all day with no start

[boosted91rex]

or if the intake cam broke seen that happen once or twice
