my del sol would shut off when I was low on oil

civicdx1

i check oil ,oil is fine.im gonna replace the ignition module and coil ,to see what happens.

civicdx1

just change coil and ignition module in the distributor,still wont start.

Mines did that too and turns out it was the fuel pump

civicdx1

i change the ignition module and coil and it din't start,i tried againg after 15 minutes and it started. i just put in a walbro intank fuel pump a couple of months ago.could it go bad that quick? my fuel pressure is at 40 ,thats the way it was before having problems too.

dude. put your fuel pressure at 50. 40 is a lil low turboed.

civicdx1

how would i do that?

are you sure the main relay is fine? when mine went it was intermittent, so if I bench tested it it worked, but if it was hot outside it wouldn't work.

when the car's not starting smack the main relay hard and try again. if it starts right up it's the relay...

my car is doing the same thing

BoostedEG6

sounds to me that you have a wire lose somewhere going to your fuel pump. when I put in my fuel cell I had that problem..... but I know you dont have a cell but I would check all your conections to your fuel pump just to be on the safe side

My car did this but im running an OBD1 app. But the problem with mine was at the ecu. The the was Ingniton Input wire....Somehow it came undone from the vacf and the car wouldnt start.......You could have a loose wire.....Also check your ECU, I worked on a civic last night.....Would start, but it had fuel and spark....it turned out the ecu fried....check them out

tthame1

Check your obd-II to I conversion harness and check the solders on your ecu. Either of those could cause that problem.

civicdx1

well the car worked well today.but it might be the conversion harness since i did buy it used,and it was splice into by previous owner.ill keep u guys posted.

Coil!

tthame1

Are you running stock ignition and coil or is that upgraded? Because if it is upgraded, check the wires going into the distributor and make sure that you have good connections there, that could also be the problem.

civicdx1

im running stock ignition,and i just change the coil.it turn off this morning again but it did start after a couple of minutes.

Do you have a fuel pressure gauge?


If you don't, immediately get one.

I had a very very similar problem in the past. Turned out to be my brand new Walbro that pooped out on me somehow.---And I didn't know because I had no way of telling if I had sufficient pressure to keep my engine running.

Same exact symptoms as you.

I spent nearly $400 replacing other parts before finally narrowing it down to my fuel pump.

civicdx1

yeah i do have one and it reads 40.

Surftouch

check your harness if somone spliced into it and you got a loose connection that will cause it to do what its doing....mine did the same thing cause my friend spliced into my harness and i had a loose connection....check the Ingition input....thats where my prob is....If it has good connection it would run, but like if i stoped it would not want to start...check out ur harness im sure you will find something!!

mugenhatch92

well mine shuts off to, but it is because of a cracked piston.....

probably what yours is... do you have your oil line from the valve cover going back into the turbo intake?

or did you get bad gas and it caused denation and blew your motor?
