There's no fuse because that it the PGM FI key relay strength it as soon as the an essential is rotate on right here is a guide to aid you test the relay and also diagrams below to display you the location. out the diagrams (Below).

In fuse dashboard under dashboard behind left kick panel. Fuse #2 - 15Amp fuse controls PGM-FI key Relay & Fuel Pump.Thanks for using Com!

fast question no start replaced a most parts as soon as probing yellow wire to fuel pump assembly. Supposed to supply 12v to pump I have res come grd Is there an alleged to it is in resistance to ground there.

Relay is good checked several times pump does not prime yet provides pressure as soon as cranking ecm come on energizes relay after part time tinkering I determined to look because that a base fuel pump. Within grounded together I have had an concern like this through a different vehicle. Removed 3 pen connector in ~ fuel pump. Probed the yellow cable which gives twelve volts to the fuel pump this test was done with harness d/c in ~ the fuel pump in between yellow wire and also ground I have approx 50-150 ohms.
auto wont start I have actually tested injectors, relay, dist, lid rotor wires ecm pulses injector wires I have actually 12v warm to injector wires. Tested all fuses. Reset ecm. Blinking s light and also no start
1991 Honda Accord 4 cyl automatic I have a "91 Honda Accord the quit functioning while driving under the road. I have replaced the battery, alternator, spark plugs and wires, distributor car and also rotor button, and the ignition coil. The vehicle will cranks and turns end easy, however will no fire. We carry out not hear the fuel pump revolve on so wanted to check the relay the the fuel pump. Whereby is the fuel pump relay situated on a "91 Honda Accord? and also is the fuel pump in the gas tank?
I have actually spark and fuel to rail but only once cranking. Sorry for so numerous replies but including all that I have done changed ecm remained in water changed dist. Replaced main relay due to the fact that I foolishly thought with blinking s irradiate it was bad codes 7 and 8 native tcm both shift solenoid codes
Dunno the full resistances that the fuel pump motor windings-as you"ve examine it and also its 50-150 ohmsDo this strength the fuel pump straight from the battery and see what happens
Ok just a hick update sorry took so lengthy to get back here.I pulled injectors have great spray all four plugs firing. Firing bespeak correct. Manually cranked engine by hand come ensure distributor seated appropriately it is.S light quit blinking. Tho no begin checked ect. Tps. Iat. Seems prefer my map sensor isn"t mirroring correct return voltage for 0 in/hg only have.19v returning which shows up to be what it must read at complete vacuum.I don"t have a vacuum pump so ns can"t test various other voltage readings.I think i am going lil crazy below thanks for her time PS bout 150 psi every cylinder compression i really am shedding it this is the second new distributor I placed in since the very first one I obtained had a negative reluctor.I to be sad
This accord has a habit of not starting when the fuel level goes below half a tank. Above that no problem, however as shortly as it gets below that mark it will die or if you rotate it turn off it won"t start again. Readjusted fuel pump, cleaned tank, replaced fuel filter, changed pump relay. Any assist would be appreciated. Not lot hair left on mine head indigenous this one. Thanks. Tigerguy05
If the fuel sending unit has actually been readjusted and that is new, the nest suspect will certainly be the coil behind the gauge or the wiring from the fuel tank to it.
ns should have actually mentioned that ns did traction the valve cover every the mechanical factors for the to not run space sound the rebuild was done by wonderful machine shop here yet I walk visually verify the valve time
Is the fuel pump coming on and has the exactly fuel pressure? I need the fuel pressure before I can continue to aid you-

Ok an initial of all I just want to say thank you.I have been therefore frustrated v this car I have about 15 years experience as one ase tech and have never had actually this problem before. Course I never was very great at electric so here"s a breakdown of some updates. The s light no longer blinks the fuel pump currently primes correctly I have actually 43psi throughout prime and also while cranking. It seems I have resolved alot that the electrical problems removes and also unstuck egr pintle sensor and also map sensor i m sorry was sending out a complete vacuum signal come the ecm. Now has the suitable 3 volts. Here"s the kicker the vehicle ran albeit not great before I changed the distributor.I have actually a sneaking apprehension the distributor is negative this was the 2nd one I got from napa the very first had a negative reluctor i pulled the injectors come verify nice conical spray.I have actually spark. Mechanically the time is on that really wants to start yet just won"t
