Hello and Welcome to Justanswer, My name is XXXXX XXXXX I am here to try and assist your with your question

Steve :

hi again

Steve :

still trying to get your truck to start?

JACUSTOMER-8y0hy3fn- :

battery is fully charged. engine turns over but will not start. eventual thebattery is drained. what other options do I have?

Steve :

have you checked for spark and fuel pressure yet?

Steve :

does the check engine light come on key on engine off?

Steve :

are you there?

JACUSTOMER-8y0hy3fn- :

the truck has recently had a tune-up. it has 89463 miles. have not chek for spark or fuel pressure. the gas tank has over 12 gallons no the engine dont come on

Steve :

If the check engine light does not come on key on engine off could have a bad computer relay in the fuse box under the hood

Steve :

click on the blue link for location of relay in the fuse box and change the relay out with another relay. It is called the pcm power relay swap it with the blower motor relay and see if it will start.

JACUSTOMER-8y0hy3fn- :

do you think this is a fuel pump problem why the truck try to start but does not. i dont think it is a timeimg belt problem because it is metal and I dont see it breaking. I am trying to find what I can check to find out this problem. I have not had any problem with this truck othe than regular meintenxce.

no I would swap out the relay yourself it will save you some money and it is not hard to do

JACUSTOMER-8y0hy3fn- :
