Car playing games with me???

[91rusty]

Ok.so here is how it started,a friend came and took me and my dad to a place where we replaced his timing belt on his 93 corolla,we needed to got there to use the air gun,so later when we come back and we want to go to this friend for a bbq because we fix his car,we get into our car,it has been sitting less than 24 hours,we get in,start it up,it cranks but doesn't start,ok lets wait,we had this happend before,but in 30 seconds or so it always would start and we would go,not this time,we wait and crank it again,nothing,again nothing,the motor would spin but not fire up.So my dad bieng a mechanink took the bool of the fuel rail,and told me to cranck it a bit,and surprisingly no fuel came out,nothing at all.To make it short we thought someone stole the fuel out,we went and got about 10 liters,started it again and fuel was still not coming out.Now my dad was pissed,cause we really needed to go,he started to chek all the fuses,under the hood and drivers side,they were all ok!!!First thing that came to our minds is its the freaking fuel pump thats gone.
So we leave the car there and take a friends car,about 6 hours later when we come back,i try to start it for shits and giggles cause dad needs it to go to work,and u woudnt believe it,the Bicth starts right up like nothing ever happened????????????????????????????????
U guys have any idea what could this be,after she warmed up the ilde was really low,like 250-350 rpms,but otherwise she was fine!!!
does the main relay have anything to do with the fuel pump???

Yes. I'm guessing you need to replace or repair yours.

[turboAccordHSF]

[91rusty]

R u guys sure its the main relay,i just dont know if it has anything to do with the fuel system,and if how can i repair it?

[turboAccordHSF]

well seems like your car is fucken with you i can't say i know the solution cuz i don't know how your engine looks like or I can't even inspect the car over the computer you know......but hey if it happens again check everything....spark plugs, starter battery, belts, timing belt, eveything that you think could be the problem?...

[92bently]

yeh the main relay prolly has dirty contacts inside causeing the improper voltage to the pump...if ur dad is a tech he shoudl know how to check and see if u have power at the pump and comming out of the main relay...but yeh prolly only has 6 or so volts @the pump causing it to start sometimes

It's a common problem with cb7s. The solder joints inside the main relay go bad. They seperate when they get hot. I'd say most of us have experienced it at one time or another. You can either repair it or replace it, but whichever you choose, don't put it back in the same spot. Leave it loose and let it hang lower than it was. Do a search, there are dozens of threads about it around.
