I am having a very similar issue with my EFI setup and am finding information in this thread very helpful but have a few questions that should help the OP and myself.
How do you troubleshoot these issues short of replacing things one at a time?
IE: 1. Issue with Spark plugs or wires - Can these be tested without replacing them to know if they are good or bad?
2. Coil - Again, anyway to test without simply replacing it?
3. Fuel can be tested with pressure gauge but if it is overheating, then is the only option to check heat after it's been running? Should you hear the pump turn off at any time or shouldn't it run all the time?
Just looking for more help on exactly how to troubleshoot some of the things you guys have mentioned.
Appreciate the help.
