I have a 94 ej1 that I put a D15b2 and it's receiving spark and fuel, and it cranks but just doesn't start, used starter fluid and still wouldn't crank. I checked all my fuses and they are good, none are blown. Checked my grounds they are good and checked all my connection and everything is connected right and it somehow caught on fire under the intake manifold but was put out. But there was no reason to catch one fire. Any help would helpful.

 

All you need to start is air, spark and fuel so if you're absolutely 100% you have all three then you have a timing issue.

 

What exactly was on fire? Wires?

Post pictures.

 

Ditto on the timing. Recheck it and make sure your distributor rotor is pointed at the correct firing order.

Also wouldn’t hurt to check your compression

 

Not concerned by the engine fire?

 

I'm presuming he's repaired any damage caused by the fire.

 

Why?

And what do you think was the underlying cause of the fire? Electrical or fuel?

 

The poster doesn't appear to be concerned about the result of the fire otherwise I'd like to think he would be giving more details of that in order for us to help him. I have no idea of the cause of the fire. For all I know a bifta could have dropped out of his mouth when doing an oil change.
Are you suggesting more information is needed before anyone is to offer suggestions?

 

But why aren't you and K20 concerned. The OP also said this:

The OP may not have enough experience to judge the importance of a relevant observation, though he/she did find it important enough to mention.

I'm suggesting that an engine fire worth mentioning is a huge red flag that should not be ignored. OP should consider that the fire is either the cause of the problem or is related to the underlying cause of the problem.

 

I'm not concerned because he's able enough to ensure fuel and spark is there, and I gave him the benefit of the doubt that he had checked and undertook, if any, repairs. Secondly my advice to check timing will do no harm and is free. Good luck to yourself and the poster in resolving his starting issues

 

I know you are trying to help like the rest of us here, so don't take what I've said in the bad way. Tech threads are tricky to navigate.

How can you be sure? For example, does OP think the engine gets fuel and spark because the fuel pump primes and one spark plug shows weak orange spark?

Why? He only mentions an engine fire and nothing else.

 

The fire was around the intake manifold. It was put out just in time for it to make any damage to the engine or injectors or any wires around it.

 

Following your clue, post clear pics of fire location on IM.

 

Fire is the number 1 priority if a engine catches on fire. I also thought the op had already addressed that issue first and got it figure out.

first and foremost yes address the fire issue first OP if you don’t know what started, Check for a leaky injectors/ bad injector grommets etc, At this point don’t start the car but switch the key to number 2 NOT ON, also have a fire extinguisher on hand and ready with someone outside the car to be ready to extinguish. Have someone see if fuel squirts out anywhere near the area you had the fire.

 

I just checked the timing and the timing seems to be good and not ahead or behind. And I'm getting spark, fuel, and air but still isn't starting
