Hi,
I have a 1990 Integra LS which tends to stall immediately after starting when the engine is warm and/or when weather is hot. It seems that something either cuts of the fuel or air to the engine. I have replaced the battery and spark plugs. I checked the EFI Main Relay and it seems ok. Any ideas? |

Nothing is cutting off the AIR to your engine. Fuel or spark,yes. Fuel is usually the main relay,spark could be a number of things. Bad distributor cap/rotor,or igniter. > I have replaced the battery and spark plugs. I checked the EFI Main > Relay and it seems ok. > > Any ideas? > > > "seems OK". The common MR failure is not something you can readily discern by eyeball. Try resoldering it,or replacing it. (as long as you had it out,you shoulda resoldered it!) Tegger.com is a great site for info and repair instructions. -- Jim Yanik jyanik at kua.net |

Thanks very much for your comments. I will look further into the Main
Relay.

Thanks very much for your comments.
To check the Main Relay, I used a procedure as described in my Haynes Integra-Legend manual. In short it means, disconnecting the relay then connecting it directly to the battery, shorting a pair of terminals, and checking to see if it switches on another pair. However, I will have another look at it. Thanks again.

Try Main Relay, My Mitubishi truck needed this relay replaced and it is a
1990 model. <TeGGeR? <tegger@tegger.c0m>> wrote in message news:Xns9735C2B6D6905tegger@207.14.113.17... > "motor" <2000@hotmail.com> wrote in > news:ceqqf.167428$Gd6.80760@pd7tw3no: > > > Hi, > > > > I have a 1990 Integra LS which tends to stall immediately after > > starting when the engine is warm and/or when weather is hot. > > It seems that something either cuts of the fuel or air to the engine. > > I have replaced the battery and spark plugs.
