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.
Turn ignition to ON (but not to START): Click 1
Check Engine light goes off: Click 2
You now turn the key to START: Click 3
The most common symptom is that you crank, the engine starts, but as soon as you let go of the key, it stalls. If you listen carefully, you'll hear the clicks as they happen. If your ears are poor, or surroundings are noisy, reach behind the dash and put your hands on the relay to feel the clicks. A description of the clicks and when they occur is found under "How does it work?".
Yes there is on the pully on top there should be a line and it should line up with the one one the bottom pully on dohc models line both lines up on top if posible and dot and arow should line up on bottom pully.]
ps ; if timein is off ur valves will probally be warped then if so i wouldnt even fool with it unless it has value to u

Generally speaking, its supposed to do that. The fuel pump(s) is powered by a relay that turns on for 3 seconds when you turn the key on. If the engine does not start and produce oil pressure, thats all the power the pump gets. If you were in a wreck the pump would shut off when the engine dies even with the key on to prevent a fire. You would need to jumper the relay to make the pump run beyond the 3 second time.
It's possible. You will have to test the pump(at the fuel tank electrical connection) to see if it's getting current when the ignition is turned on. If it's getting current, the pump is most likely bad.
Replace the fuel filter first. When you turn the key on, the fuel pump should run for a few moments, then turn off. If it keeps running, then replace the pump as well. Suggest having the fuel system pressure checked at the engine itself. Hope this helps!
Careful doing this. Disconnect the fuel filter line between the tank and the filter. Have a bucket or equivalent below to catch incomimg gasoline pouring out. Have some one turn the ignition key to on. Do Not Try and turn the key to START!! Just turn the key to the ON position. This will kick in the oil switch to feed gas to the engine for 5 seconds. If gas comes out the pump works. Reconnect the filter and try again. If no start is happening still disconnect the fuel filter's line towards the front of the engine this time. Turn the key ON. If gas comes out the filter is fine. If not the filter is clogged up fully
run scanner for trouble codes, some auto parts stores will do this for free,check fuses, check for fuel at fuel rail, if not check fuel pump relay, you should here it click when key is first turned on, if not try to bend tabs slightly to make good contact, if no click, replace relay if so turn key off then on listen in tank with cap off for whirling sound if tank, if not could be fuel pump, sorry
