91 F150 XL. Check engine light problems

Just got a F150, its 1991, runs good but the check engine light will go on and then off then go on then off every 10 minutes. What should i do leave it or buy the code reader?

Ford Fuel Injection How To Run a Self-Test Here is a link on how to read the codes without a code reader, however you could buy one for around $30 to make life easier.

You can pick up a code reader in your desk drawer. A paper clip will get the job done.

There's one called the Innova Equus 3145 that a lot of people like (I have one and I recommend it to everyone with an OBD-I Ford). It's much easier and far less error-prone than using the paperclip. I see tons of posts in this forum where people misread their codes or I at least get the feeling they have. The code reader removes all doubt.

Yeah, I'm one of them. Did it five times and pieced together something that made sense.

ok, ill try that one out, also, when i push the clutch in the brake goes in a little as well, and theres a little delay in the gas pedal. I'm gonna replace the serpentine belt and get that code reader. Also my friend knows whats causing the delay in gas so he's gonna help me with that and thats about it. my brother said a mount is probably broken and thats causing the brake to go in as well, we have a welder so i'm gonna weld that up. But one problem that i'm most concerned with is it has two gas tanks, the front doesnt work, does anyone know why it might not work or will i just have to mess around with it and figure it out. Thanks for the advice guys, your lots of help.

My guess for the front tank is that the in-tank pump is bad. However check that you have 12v going to it in case the selector switch or wiring is bad.
