problem starting

[oramac_eg]

Hi everyone.
Wondering if anyonehas had the same problem happen. So my truck has problems starting I have to crank it for a couple seconds before it starts what could be the problem? It has a new battery, fuel pump. Did the tune up oil, spark plugs, wires.

Try cycling the ignition keys 3 times for 5 second intervals and then try starting it. If it starts right way, then you loosing the prim fuel pressure when the engine is shut down.

That would indicate a bad check valve at the fuel sending unit which is letting the fuel to drain back in to the gas take and the fuel pressure to drop when the engine is shut down.

Good luck and keep us posted.

Thanks you Molson02536.
I tried doing what you said. Problem is its hard to do it. Sometimes when the truck sits for a while it will start right up or it will take long to start. I never know if it is or not. I did try it tho but it struggled a little to start. Once its on and I turn it off and turn it on again it has no problem starting. I checked the FPR and it's still good.

I have 2 engine codes a P0442 and P0300

Technical DescriptionRandom/Multiple Cylinder Misfire Detected

What does that mean?Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.

A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.

SymptomsSymptoms may include:
•the engine may be harder to start
•the engine may stumble / stumble, and/or hesitate
•other symptoms may also be present
CausesA code P0300 may mean that one or more of the following has happened:

•Faulty spark plugs or wires
•Faulty coil (pack)
•Faulty oxygen sensor(s)
•Faulty fuel injector(s)
•Burned exhaust valve
•Faulty catalytic converter(s)
•Stuck/blocked EGR valve / passages
•Faulty camshaft position sensor
•Defective computer
Possible SolutionsIf there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Technical DescriptionEvaporative Emission Control System Leak Detected (small leak)

What does that mean?This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

SymptomsYou likely won't notice any drivability problems.

CausesA code P0442 most likely means one or more of the following has happened:

•A loose or improperly affixed gas cap
•A non-conforming gas cap (i.e. not factory/original brand)
•A small leak/hole in a fuel vapor hose/tube
•Other small leak in EVAP system
•Faulty vent o-ring seal
Possible SolutionsWith a P0442, the most common repair is to:

•Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
•Otherwise, replace the gas cap, or
•Inspect the EVAP system for cuts/holes in tubes/hoses

So about a week ago i stoped by the dealer and picked up one of the lines that goes from the gas tank to the evap canister. I broke it when i was putting the gas pump a couple months ago. So check engine light turned off i was semi happy still had to crank it for a couple seconds to start. About 2 days ago check engine light came back on 4 codes 2 were the same. P0175 and P0300. the same day i fixed the line a filled up the tank all the way next morning a seen there was something leaking so i checked it was gas from the tank is this normal? since truck was at an anle in the drive way

So i just did the FPR test took off the vacume line fuel was coming out? So if im not mistaken from what i have read the FPR is bad?

Changed the FPR and now no check engine light truck starts right up. Just hope it stays like that.
