    1989 Ford F 150 starts intermittently
    1989 Ford F 150 with a 4.9L engine, fuel injection, sometimes when I turn the key on you can hear the eletric fuel pump charge up and the truck starts, but many times when the key is turn on the eletric pump does not charge up and the truck does not start, it has a new eletric fuel installed. The maintenance book talks about fuel relay, do not know how to locate. Any thoughts.

    Yes, you want to remove the fuel pump fuse and the fuel pump relay (normally 5-pin), in the underhood fuse/relay box, and clean the contacts. Lightly coat the contacts with dielectric grease. Locations are spelled out in your Owner's Manual. I've seen major corrosion problems on older F-150 fuses and relays--so much so that current won't pass. Should be an easy fix.

    It would be a good idea to, one at a time, remove and clean each fuse and relay. Gently pry each relay out. I use a special rubber-tip pair of pliers for removing these relays--they can be stubborn.

98 Honda Accord Starts intermittently [ 1 Answers ]

I have a 98 Honda Accord that starts at times then won't start for a few days. I have a flashing maintenance light for about 5 seconds after the failed start and a flashing green key for about 2 seconds after a failed start. I smell gas so I don't think it is a fuel pump/filter issue. Any ideas?

HELP! 95 civic ex barely starts, cuts out intermittently [ 4 Answers ]

Hi all. Having a problem with my 95 Civic EX. Idles beautifully when it starts, but cuts out when you step on the gas, especially if you step on it hard. If you step softly on the gas you can slowly manage to get around to a quick location, but when the car heats up it is almost impossible to...
