I have a 2000 Ford F150 which just recently got a brand new engine core and with the water pumped fixed plus compressor.

Thinking well the truck should start with no problems yeah for the first couple of weeks but then its failed to start.

I had to sit there for awhile until it fired up. I went to the mechanic and says its the not the battery or the starter and just did re-calibrated the fuel which then the next week it failed again (Mechanic is trust worthy).

I think it needs a new fuel pump. Any ideas on what's going on?

 

whats it doing... not cranking... cranking... if its cranking but wont start.. i would start with checking fuel pressure.. if you have fuel pressure you have to check spark

 

it will try to turn over but if fails to start and like after a few trys then it will fire up. sparks are brand new (i think).

 

have you change the fuel filter??.... ran any sea foam through it

 

Sea what? lol

 

haha.... sea foam...... google it..youtube it..... and search it on this forum .... its good stuff
