Alright, problem with my girlfriend's 88 CRX Si. The car starts perfectly fine first thing in the morning or if it's been sitting for a while, but if you drive it for a bit, turn it off (like to get gas at a gas station) it just turns over won't start after.

It used to have a "hunting" irratic idle where it would bounce from 1000-1800~ rpm but I fixed that last night by cleaning the IACV with some carb cleaner. A couple times the check engine light has come on while driving, but it only stays on for a few seconds then goes off. I checked the ECU and it was a code 7 - TPS sensor. Could this be the source of the problem?

Also, when the car won't start, if I prime it a few times (put the key in accessory mode for a few seconds, then turn the key back to off, then repeat a few times) it will usually start right up. That to me sounds more like fuel pump or main relay... Is the TPS code just a coincidence?

Please help!

 

probably main relay...go to the junkyard and pocket it or find one on here...parts supplier cheapest i found was 40 dollars

 

Are the main relay's the same for all EF's? Or for all PGMFI's anyways?

 

the main relay are the same for the ef/ed's I even think the eg are the same but not positive. I had a The same problem with my integra, I changed the ignitor and the relay at the same time and it never did it again.

 

Fix it yourself. Save a trip, tiem and $$

His instructions say to remove old solder. This is the right way to do it. I just add solder, worked fine for me.

 

Right on thanks for the help guys, I'll give it a try this weekend.
