Question about 1986 Honda Civic

86' si starting problem

The fuel pump will not come on from a hot restart. The car always starts from cold and the malfunction is random. When running, the car never quits and the "relay" is new. Give the car about 25 min. of cool down and the car just starts?...

I have a Kubota B2710 that acts like it's starving for fuel and after about 30 seconds of that it clears up or you can cut it off and and restart it and it runs fine for about a minute before it starts...

check if cold start valve or sensor not malfunctioning,choke unit set to rich. negative valve clearance normally creates a similar problem.Importantly engine management wires should be checked including efficiency of spark.

Engine starts cold, doesn't always restart or restarts after a long period

Fuel not reaching fuel rail, battery low or discharged, or defective spark plugs.

Suzuku SX4 starting problems - fuel pressure

intermittent are hard to find.
as they say" if it ain't broke, you can't fix it" applies
but in truth, we lay in traps to find this.
this is true with all machines, not just sx4
facts: (random no starts) but always cranks fast.
only fails cold engine. never hot. (does restarts hot work?)
seems yes.
seems you have full 12vdc power at all times.
seems the engine is ok. as it is not heat rlelated or the classic hot soak fails.
so what is it.
well, its 1 of these.
1: lost spark, simple tests, do so when failed.
2: bad fueling. (too much or too little)
the tests for each failure are dead simple and work on any engine.

Hard start on hot restart

Try to check your fuel pump pressure, or replace the fuel pump

1986 Subaru GL 4 Door Sedan problem: Shuts down after fifteen minutes of driving. Let sit for 1hr restarts normal for another 15 min.Temp. Normal gas meter always at more thn half Opinions heard Fuel...

Fuel pump heats up and malfunctions??? HaHa that's a good one. Tell the dope that told you that, I said the fuel pump is only going to get as hot as the fuel it is sitting in....or at least, lets hope so, unless you like to see bombs go off!

The best advice I can give you is this:
1. Check to see if there are any fault codes in your computer. (On an '86 Subaru, the computer might not be very smart, but check it anyway.)

2. If there are no codes, run the engine untill it stalls, then pull one of the spark plugs and see if there is any spark when you try to start it.

3. If it has spark, then you should check to see if it is getting fuel.

You have to find out which system is failing (Spark or Fuel) before you can even guess what is causing the problem.

Hard start when hot 98 ford windstar with 3.8

Try replacing the fuel filter also Has it had a tune up? they need to have the plugs replaced at 100,000 if the fuel filter does not work then the most probable cause is the fuel pump is losing pressure when hot. The pump warms up and the check valve fails to close all the way allowing a now fuel or fuel starvation.

Sometimes wont start

it may have a bad check valve in the fuel pump try this when it has to crank for a long time to start turn key off wait 5 seconds turn key on wait 10 seconds and rpeat 3 times if it starts right up the problem is the check valve in the fuel pump if not you need to find out if it si spark or fuel but sounds like it is the check valve sticking in the fuel pump
