EA82 cold start problem

Recommended Posts

1993 Loyale w/EA82 SPFI. Normally starts instantly and runs very well. Twice recently it has failed to start. Starter cranks over well, everything sounds fine, except it doesn't even try to run. If I squirt some ether (yeah, I know....) in there and hit the starter, it fires up almost instantly. After that, it runs great. Acts as if the SPFI isn't spraying fuel into the venturi, to me. Ideas? Thanks, y'all. cnc

hi i just bought an 88 wagon with spfi i believe. and my factory choke has crapped out on me i think. i live in wa and its in the 30's in the morning. so when i go to start her up in the morning it starts up fine, gets to about 1200rpms and then drops back down and dies . does this everytime so i have to give it some gas and let it rev at 2000 for a bit then i let off and it kinda wants to die but idles at 500 for a bit then slowly idles higher as it gets warmer ... any ideas would help. thanks

So this whole setup is fuel injected ? Everything says Hitachi on it ... Which is a carb right ?

And I didn't see any hoses unplugged, this looks like it's missing a hose though

And I forgot to mention that it works fine after I've driven it for 20 minutes or so . Like if I go to the store and go to start it back up it it revs up to 2000 on its own, stays there for a sec then drop back down to 1000 and idles fine.

My 1992 Loyale never started and went to 2K rpms then dropped down... always to about 1200 rpms then down to ~800. However my carb EA82 requires me to hit the gas, crank ot... it'll fire up to 2000 rpms and slowly climbs to 3000rpms. At 3000rpms ill hit the gas and the rpms drop to ~800 and car is ready to drive...

 

I thought SPFI was better than carb because you start and go but seems like other spfi cars have to warm up exactly like my car does.

Hose is for the PCV system, and is the "Fresh Air" intake.

 

With it unhooked, unmetered air, (air not passing thru the MAF), was intering the intake system of the engine. ECU couldn't account for that air, so no extra fuel was added, hence the stalling.

 

Fuel injection doesn't need a long "cold start/ high idle" like carbs do.

Your's sounds like it's right.
