Hey guys need some help. Here's some background it has 240,000 miles I've done all the basics plugs wires fluids etc. It would start fine but had a rough idle, if I wouldn't warm it up enough and start going it wouldnt have power and stall out when that happened it would take a while to start up again. I had no issues starting the car until recently now it takes about 20 seconds to start, actually it won't even start now lol, the truck turns over fine I get spark and fuel and it wants to start but it just doesn't, I'm not really sure where to go from here though any help would be appreciated. Thanks.

 

just curious how you confirmed its getting fuel ?

 

is the spark fat and blue ?

or weak, yellow and erratic

 

Could be a couple of things unless you've confirmed some things. One could be either your tank fuel pump, you have a leak in your fuel system. I'm going to rule out the electrical if it can turn over for 20sec then it's probably ok. I would say more than likely fuel. It could be your ignition system too. How does the exhaust smell once she's turned over?

 

Dustrider- when I was checking for spark I did not disconnect the Injectors or relay so some fuel shot up the plug hole and the spark was weak now that I remember.

Kryptoroxx - it used to smell like fuel whenever I turned it on, I did replace the Injectors as #1 was leaking after that it was fine it even helped the idle a bit, but know the fuel smell is back because it is not turning on.

I've also changed front o2 and gas cap, and also had my cat stolen, I've already replaced it though.

Next thing I'm doing is compression and leak down test and we'll see how that goes.


Thanks for the help keep the input coming.

 

If the spark looks weak I would look at ignition functions such as the Crank Position sensor and Coil Pack, ECU etc

could be as simple as a corroded connector

 

any mil codes?
