I have an 1984 Corolla that has had an engine swap done to it. The engine was an SE2. Everything has been reconnected properly according to vacuum schematics. The cylinders get fuel. The plugs have all been checked for gap. The wires output spark. Throttle body sucks air. Why doesn't this beast fire? It has the essentials to fire and start. It fired once for around 10 seconds the first try, then it died and wouldn't start again. It has gas, and a fully charged battery. I have exhausted everything i could think of as far as troubleshooting. Any help would be greatly appreciated.
I'm not quite familiar with 2SE, but I will just throw in some question (idea?) to see if it help:
Did you switch the ignition system as well or you still using the old ignition system from the 4AC (Assume yours is a 1984 Corolla, not 1984 Camry)?
The 4AC originally come with two vacuum switch, temperature switch and a oxygen sensor with the emission control computer, did you swap them when you swap your 4AC to 2SE as well?
The original ignition system is being used. The computer was switched. I think the rest of the sensors were left alone.
Engine require air, fuel and fire to run.
For fire, maybe the original ignition (which is for 1.6L 4AC) didn't have enough power to fire up the 2.0Liter 2SE?
For fuel and air, did the 2SE that you install is EFI or carb? Assume your is EFI (from wikipedia) did you have all the necessary parts for the engine (ie: engine computer, bigger fuel pump, all the electrical stuff for the engine since it is EFI) since the original 1984 corolla is come with a carb 4AC engine?
The thing that has me stumped is that the engine is getting all of these things. It has spark, and ample spark at that. It has air, i verified the MAF was opening. It has gas, the spark plugs have gas on them when pulled. The original engine was fully functional until the engine siezed.
The one thing i can think of off the bat is that the engine may not be completely grounded. Evidence of this is that there are no "spark" marks on the spark plugs.
so did you start off with a 4ac? im leaning with what ea8631 did you do all the efi stuff, and what fuel pump are you using, assuming you started off with a 4ac itll have a mechanical low pressure pump above the valve cover, instead of a higher pressure, efi in tank pump?
The pump is a high pressure in tank pump. All of the efi stuff is off the old engine.
I'm sorry but I'm lost here, there shouldn't any efi stuff of the old engine since the old one (4ac) is carbuated. Unless yours is 4AGE which is different story.
Also, I can't image that you can use your original ignition system from 4AC to 2SE (maybe I'm wrong if someone know more in 2SE) since the component looks totally different?
Do you think it is possible to post up a picture of your current engine bay now?
Ok, as mentioned before. The old engine was a SE2. It was fuel injected. The engine that was swapped was identical. I thought i made this clear. The problem is the engine has all the essentials to run, and will not. It makes no sense. The only thing i was in doubt about was the grounding of the block itself. I was not present for the engine install, only the aftermath. I have gone over ever vacuum line, every essential electrical component. Why will this thing not fire up? It has fuel, air, and fire. What else does this car need? I could understand if it ran for a second and then died. This will not even attempt a start.
