when i turn my key on the fuel pump primes normal but when i go to start the car it wont start the first time i crank it no matter how long i hold the key on ... but when i turn the key off and turn it back on the pump primes again and the car will start normal. it has been like this for a long time and my second question might sound dumb but if i leave the key in run and dont start the car is the fuel pump supposed to primne every like 10 seconds? if not waht would make it do that. any help would be great. thanks alot
