engine takes almost 8 seconds of cranking beofre it turns over

[sreilly77]

ok i just had my fuel pump replaced by my mechanic on my 95 town car (kind of hard to do it myself with a foot of snow on the ground haha). the only one was completely shot. here is what is confusing me. after starting the car and having it run for whatever length of time, i can shut it of and then start it right back up again without any problems. however, even if i just let the car sit for like two minutes, ill go back outside, turn the key, and the car will crank between 5 to 8 seconds before the engine finally turns over. im worried because if i let this go over a period of time, my starter will burn out. what is going on here?

sorry i definitely can't type, i meant to say the OLD fuel pump not ONLY fuel pump. but i should also mention that it doesnt matter if the car is hot or cold. if you let it sit for even like a minute, it will take almost 10 seconds before the engine turns over.

go back to the mechaic and tell him he screwed up and fix the pump properly

have u checked fuel pressure because it shouldnt drain back into the tank i beleave theres a valve that shouldnt allow the fuel to drain back into the tank but im not sure does it start up first thing in the morning after sitting for the night?

[sreilly77]

yea, it starts up fine in the morning, just its hard starting. i did take the car back to the mechanic and they put in a new fuel filter and fixed the fuel pressure issue. but it is still not right, so i am taking it back again tomorrow and they are going to put another pump in and they are going to fill the tank because i had to drain the tank under 1/4 twice now. so yeah this sucks.

General observation --

Following the line of thought were the pressure should'nt drain back to the tank, will it start right up if you first wait, Key On, for 10/15 seconds before cranking the starter?

This thought would assure the fuel pump pressurizes the rails before the starter cranks, thererfor proving/disproving the fuel is draining back to the tank.

[sreilly77]

i did try that, just turning the key to the on position and giving the fuel pump time to pump up. the same symptoms still occur. i might add though, however, when i do get the car to run, and then shut it off and immediately turn it back on, the car will start right up. so the fuel is staying in the rails for a short time. i am wondering if the pressure is not where it is supposed to be probably because the new fuel pump is falty. i think the fuel pressure is around 15-20psi i'm not 100% sure. well i'm taking it back to the mechanic tomorrow. it will be fixed for free since this is the third time in the past 5 days that i had to bring this car back

one other thing i might add. i have noticed that since these problems have arose, every time i hit the gas pedal either at a light or a stop sign, i notice puffs of blue smoke coming out the back from both exhaust pipes. this happens when the car is idling for more than 30 second or so. and it doesn't matter whether the car is in park or drive. and the engine is hesitating slightly. does this have to do with the fuel pressure problems that i am having?

when i say this, i mean it as that this is the normal fuel pressure for the car when the problems i am having are not present.
