1975 1.8L Ljet injection. Car is hard to start. It takes 3-4 tries and some time a shot of starting fluid. Fuel pressure gauge reads 30 lbs. in engine compartment. The rpm rises to 1800 rpm for about 15 seconds, then the idle hunts between 500 rpm and almost stalling out. After the engine warms up it runs and starts as normal. Vacuum hoses are tight. Comments?

Installed new intake runner gaskets, intake hoses, and new injector seals. I checked the injector plugs 3 times to be sure they were right. Checked the cht sensor by grounding the harness connector to the battery. Swapped out the dual relay, nothing changed. Swapped out the AAR valve, nothing new. It needs starting fluid to get it to start. Then it will restart with no problem . Fuel pressure was 30lbs. at idle when it ran before. It starts and then stalls out. After all the work, it's worse, not better. Where do I go rom here? (IMG:style_emoticons/default/headbang.gif)

If I disconnect the AFM from the harness it does the same thing: starts up, then died See if the fuel pump is getting 12 volts after it dies; that will tell you whether the AFM to dual relay connection is good |
