Alright guys, I have posted about this before, and Im still having problems. Got a 00 Ram 1500 w/360...when I go to start it after it has sat for awhile, it takes longer to start. It will turn over like normal (not slow) but takes about 5 secs to start up. My fuel pump is kicking on. I have noticed when I take the cap off the shraeder port, some gas comes out, like its leaking pressure a little bit. I replaced the valve core in there, and it still does the same thing. I need to do the Hughes plenum upgrade...would a blown plenum cause slow starts? TPS? IAC? Im lost. The truck runs great, just slow starting.
Any help would be awesome! Thanks

Mines actually doing the same thing, iv got new plugs, wires, rotor, cap and the battery tests fine but for whatever reason it still doesnt want to start, and sometimes it will spin over then kick off almost like it's airlocked ? any ideas cause at this point i got no idea.
if its got **** or tires your bound to have problems eventually

with the truck running, check out the evap purge solenoid. it is behind the passenger headlight on the fender, it has a green valve cap on it.
when mine is running it has a continuous clicking noise that you can feel if you put your finger on it.
another way to check it out is to remove it and try to blow through one side, then the other. if you blow through it and it doesn't plug up then it is probably bad.

This morning I mashed the gas pedal while cranking, and it still took awhile to start. Does that mean its probably not my IAC? I will look up procedures in my Chilton for checking the IAC, MAP sensor and TPS. Also need to find time to take it to the auto hobby shop on base and check the fuel pressure. I wanna get the hughes and SCT, but need to figure out this problem before I spend money on goodies.
Ok, cool. And when I shut it off, it shouldnt drop very quickly, correct? I will check the evap canister too. Before long, I wont have anything else to do to my truck...im gonna get rid of the death flash and do the hughes as soon as I figure out this starting issue. I need to do some searching and figure out what the best way is to get rid of death flash and get good performance.
fuel pressure should come up very quickly to 49 psi and maintain there whenever its running. when turned off, it should bleed off v-e-r-y slowly. when turned back "on" it should pop back up quickly.
if you suspect any vacuum leaks, then as a test - disconnect ALL vac lines from the manifold and cap off the manifold ports. this eliminates the possibility of downstream leaks. obviously it disables those downstream devices, but its a quick way to test.

shop around. if you buy a new one, try to get it for $250 or less. if you buy one used, be sure you understand how they work and the VIN locked process and guard against buying one that's VIN locked, otherwise you're hosed.
So, I hooked a guage up to the fuel rail, and Im getting 50 psi while its running. And an initial 50 psi when the key is turned on, but it bleeds down pretty quick with just the key on. Holds 50 while running. Bleeds quickly after shut off. Any suggestions?
If it bleeds off really fast then the fuel pressure regulator on top of the pump is no good. You might be able to get a replacement at the dealer,but you still have to drop the tank to get to it. Might as well get a new pump and do the whole thing at once.

Fuel pump/filter? i had the same problem with my truck i would have to crank it for a lil bit for it to fire. Then last winter on the coldest day of the year my fuel pump died. Had a new one installed and ever since then it starts right up.
