Question about 1991 Honda Civic
Like i said-the engine will turn but will not start-have checked the fuel pump-seems fine, when i disconnect the fuel line fuel will come out when the ignition is turned. when i disconnect the line leading out from the pressure regulator and turn the engine i get a steady stream of gas(not sure if it should do that). spark seems fine. wondering if it could be the timing belt-is there an easy way to check without tearing the whole thing out?
1991 Civics have a problem with the main relay
EFI Main Relay (PGM-FI Main Relay)
On older Hondas, this is the most likely cause aside from the ignition switch. Testing and fixing is involved enough that it needs its own pages.
The Main Relay will click three times during the starting process. When problems arise, one of those clicks (usually the third) is missing, making those clicks a handy diagnostics tool.
If you consistently hear/feel all three clicks, the Relay is fine. DO NOT REPLACE IT.
Where is the PGM-FI Main Relay and what does it look like?
How does it work?
How does it break?
How can I test it?
How can I fix it? (1) (external link)
How can I fix it? (2)
Another sure-fire way to confirm that this is the problem is to pull back the carpet under the passenger side glovebox and you will see a red LED. Turn the ignition key to the on position (all lights on) and then count the number of times that red LED flashes. If it flashes 16 times before it pauses and flashes another 16 times, it is definitely the main relay.
