Customer Question
1986 f150 5.0 efi...

1986 f150 5.0 efi driving down road started running poorly relay clicking . Took truck to shop mech said earlier bad changed it messed up next 2 ecms . Got truck back from shop . Did basic parasite load test and test for shorts grounds and opens on primary power cables. Last thing shop mechs told me was one eco ran injectors all the time and one eco ran fuel pump all the time.

Mechanic's Assistant: How many miles are on the car? Has the car been starting normally?

150000, had been starting and running fine, problems started all of a sudden.

Mechanic's Assistant: Are you fixing your F150 yourself? What have you tried so far?

I’m looking at it myself because of limitations where I live , but I am trying to rule out any possible primary power issues including but not limited to relays and relay bases.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Just that I’m in a small town in Alaska not many resources.

As I find out more history about vehicle it seems when it would start running bad they let it sit overnight. Next day it would start and run. Or if they changed battery, ecm, it would run fine for a day now fuel pump on all the time.

What Customers are Saying:

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
