99 Dodge Ram 2500 4x4, 5.9 gasoline V-8. Hard to start, acts like timing is wrong, starter cant turn over the engine. Then will start and run with foot on gas. New battery, new starter, recently tuned up. Unplug battery cable to reset computer. Then it will turn over and crank if you give it gas. Must keep foot on gas pedal to keep it running after it starts. I think its a sensor - but which one? TPS/CSPS/MAP?

Do you
have the same problem?

Any applicable trouble codes? You should have checked for codes before you did anything If the starter won't crank, see if you can turn the crankshaft by hand, pull the spark plugs and accessory belt/s if you have to. If it cranks good but won't start, have a helper crank it, while you visually check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure.

If it is just an idle issue, clean the throttle-body and idle air system.

Auto zone shows no codes. It is not an idle issue, it is a timing issue. After it finally cranks, I keep foot on gas pedal, but have found that is not always necessary. Will run forever, until I kill the engine. Kill it - it may re-crank with no problem or it may act like the starter cant turn over the engine.

FYI - I have not done anything because of this new issue. The starter was out because of the solonoid, the tune up and battery were because it was due, and a new O2 sensor was because of a code (check engine light). All these things were done months ago. This hard starting issue is brand new issue.

Do a compression test. Check your timing chain.

The compression check is great, the spark plugs look great (and they are new ones and new wires with new cap and rotor). If it was the timing chain, wouldnt this happen all the time? Instead - this an intermittent problem that happens usually after driving it for a while (after it has warmed Up). If it sits overnight - it will crank right up, just dont kill it unless you are ready for this issue to possibly happen.

Your the one that said it was timing? Check for spark at the plugs when problem is ongoing. If you have spark everywhere, use a gage and check fuel pressure. Your bouncing all over the place. I guess I would have to look at it.

My shop manual says that the timing is controlled by sensors that send a signal to the PCM. This truck would run from Texas to California as long as you dont kill it and try and start it soon after killing it. It may start right up, or it may act like a timing problem. If you un-hook the battery cable for a minute and try the starter it will crank up with the foot on gas pedal.

You do not think it is a sensor? Crankshaft or camshaft sensor?

This is really strange. The issue is fixed. I replaced the water pummp (not related to this issue - but was leaking from weep hole). I put back together still would not crank. The battery seemed low, so I switched to an x-tra battery from my boat. The truck cranked right up. I checked the alternator (14.5 volts) its good. I switched the batteries back to the old one. The truck cranked right up again. My wife got me an Innova 3130 scanner tool. I hooked it up, still no codes. I have test drove three times, no issues and acts like nothing wrong.

I probably should suspect a crankshaft sensor/or bad battery will show itself in the future. Will have to wait and see, but no issues in the meantime. Very Strange?

Your scanner should also give live engine data. When the engine is warmed up and running ok, write down all the sensor readings, fuel trims, everything. That way you will have some base readings, the next time you have a problem. That scanner should also have freeze frame data, shows what was going on when the problem occured. It's not guaranteed that the scanner will solve the problem, but, a good place to start.

BACK TO WHAT YOU SAID INITIALLY

"NEW BATTERY WON'T TURN OVER THE ENGINE"

CHANGED BATTERY WORKED

CHANGED BACK TO OTHER BATTERY WORKS

SOUNDS LIKE YOU HAVE A LOOSE, CORRODED CONNECTION NEAR THE BATTERY---YOU MAY HAVE "JIGGLED" YOU A DECENT PATH FOR THE VOLTAGE TO FOLLOW WHILE PLAYING W/ THE BATTERIES

IF NOT DEALT WITH/ MAY LET YOU DOWN AGAIN

THINK MAYBE IT COULD BE THAT SIMPLE?
