My 92 accord has spark and has fuel to the rail. I am thinking it is a map sensor, because when I hold the throttle wide open and spray starting fluid it seems like it wants to start. Tank is full, I hear the fuel pump and I hear, and checked the main relay. This is all while hooked up to jumper cables to my dodge ram. Still no start. Any ideas? Thanks

Even though you have an Accord, and not a Civic, perform the tests, outlined in sections A and B, in the link below:

Let me know the results.

If the Ignition Control Module (igniter) and coil haven't been replaced, I would do so. They are very problematic on older Hondas. MAP sensor failure is not common on these cars. 90% of "crank but won't start" situations are electrical-related, not fuel. However, make sure the fuel filter has been replaced in the last 60,000 miles or 4 years.
