I had the same problem with my civic, my distributor had gone bad. It wasnt lubricating properly, and eventually it died and I got a new one. There may be a break in one of the vacuum lines or rubber tubes that come off the rochester 2se carburetor or one of the many other vacuum lines. I know-I had my truck shut off and not crank up again due to a dry rotted rubber vacuum line which sometimes are hard to see or find. Have you tried replacing your air filter and breather filter. I was having a problem with my '84 S10. It would not stay running unless you kept your foot on the accelerator, especially in the mornings after it had set for a while. I simply changed these two filters and changed the air temp. sensor, (located inside the breather) and now all is well. It only cost me around $30.00.
Bad fuel? Bad fuel pump? Bad relay?
It needs to stay on all the time the truck is running.
As long as the engine is running, it is normal for the fuel pump to run constantly.
It could be your EGR valve.
Maybe your fuel pump is broke.
the pump stays running as long as it needs to to keep the pressure up. If you think it should not, check for pressure leaks in the fuel system.
That is normal for fuel injection systems.
First thing to check / replace is the fuel filter. Next suspect is going to be the fuel pump, and if it is generating sufficient fuel line pressure.
Sounds like a dud fuel pump to me. Check all the wires first . Funny though , 87 rx7 had no carburetor...it has electronic fuel injection.
Could be a bad fuel sending unit. Could be a bad fuel pump. Could be a partially blocked fuel filter. Could be a blocked injector. Your best bet is to get into the shop for diagnostic.
must be taking in extra air some where. Check for vacum leaks.
Check fuel pump pressure Possible bad fuel pump
My car starts and runs fine .Yours may need a fuel filter or pump.
Yes, that's how fuel is delivered to the engine.
Hard to start, Not wanting to run, Low power, won't stay running.
Can be, and can also be a clogged fuel filter. A fuel pressure test will verify this.
Probably a bad fuel pump.
A sump pump should only run for 10 seconds or less, and should only cycle 2 times per hour. If it is running too long or too often, you may have a drainage issue.Ans 2 - Does your sump pump have a check valve to prevent pumped water running back to the pump ?
Is there a reset button for the fuel pump somewhere and if so, where is it?
The fuel system is blocked.Clean up the injectors.
Check the fuel filter. If your pump went bad, there's a good chance the filter is now very clogged.
Coil and fuel pump are two separate systems. Should not affect each other directly. I replace the distributor and can now get the car to start and stay running. Thankss
check the fuel pump and sending unit in the fuel tank
failing fuel pump usually. check fuel pressure.
Your water pump runs off of the timing belt. Your timing needs to be re-adjusted now.
