uuuuh megasquirt. The cheapest option for an aftermarket ECU. But when you've done everything correct, the engine still will be running. CVHs are as easy/hard as other engines to run on an aftermarket ECU.

1. When cranking do you have a correct and stable CPS reading?
2. assumed 1 is working: When trying to start, do you have an ignition spark? If yes: ignition timing set???
3. assumed 1 AND 2 are ok: Are your injectors working?
4. assumed 1/2/3 are ok: Plugs wet or dry?
