How can ibfind th problem without throwimg a bunch of parts on?

I have replaced the battery and the terminal ends, idle air control valve, tested the TPS (tested good), fuel pump, ignition coil, and cleaned the TB. Scanner is popping the code P0315 (Primary/Secondary Ignition Malfunction). Any idea on how to proceed?

when it turns over the speed ometer bounces . I pulled the instrument cluster and pluged in different bulb , it would flash on then off but wouldnot stay on with key on. tried obd and it would not flash. pluged in obd under dash and it failed to connect.

ok I'm a 26 year auto technician but got a head scratcher here. Got this truck from an auction and upon inspecting why the driver rear window wouldn't roll down (its a quad cab) realized someone had gutted the door, took window motor and regulator assy. got all new componenets and installed them and all windows work except the drivers rear, if you use the rear door switch it will roll the window down but will not roll up and I get no action at all from the NEW master switch. All the little green lamps in the top of the switches are lit and using a power probe, I'm able to watch the voltages swap from one pin to the other at the window motor but it seems like its not applying a ground to complete the circuit when you attempt tp roll the window back up. I cannot find any broken wires and even checked the TIPM for a bad connection and none were found. the problem I'm running into is finding a good diagram, I have all data but the diagram is pretty vague. any help would be greatly appreciated.

As I'm driving and come to a stop sign or red light and hit the breaks it idles up and down then it cuts off. It cranks right back up with a little hit of the gas but continue to do the same thing. Also when I crank up and bout 3 to 5 minutes in park it starts idling out of control if I don't hit the gas it's go shut off help please.

wind shield wipers going crazy, some times they work, some times they do what they want. ( WTH )

The child window locks are not enabled. I noticed in the summer months when the inside would get increasingly hot that the passenger window controls would work sometimes but would always go back to not working.

It's a 4.7 liter V8. And it's burning through at least a quart a week. Haven't noticed any white or black smoke. Nor oil leaking from under motor.

After 90,000 miles the A/C just trickles cold air into the cabin. The air that does come out is very cold, there just isn't much of it. What can I do to fix this?

The Ram truck that I had purchased was debadged by the previous owner. I'd like to re-badge it with black badges, but I don't know the positioning and what badges were originally there.

Sometimes the climate control nobs will not do anything when turned. For example, I recently set the climate control to blow out at the floor but when I changed it back to blow out from the dash with the nob, the air continued to blow out from the floor. It took a while of tinkering before it finally started to work again.

From what I can tell, the compressor is doing its job, however after blowing cold for a while, the air will suddenly switch to warm for no apparent reason.

Truck ran just fine, then got in turned the key no starter action. Disconnected cables, cleaned, charged battery, reinstalled. Will not crank over, jumped starter relay and replaced, neutral safety switch, jumped starter and it does work fine. WCM where should it be if it has one. Do you have a pic or description. In advance Thank You.

Hi,

I have a 1996 Dodge Ram and I think my PCV Valve might need to be replaced. Can someone tell me if #1 in the picture is my PCV valve?

Also how would I find out the vacuum line size in #2 that I need to replace?

The truck has been sitting a couple months but my gauges worked when I started it yesterday

old pcm sn ended with AA was factory updated to AB bought reman flashed pcm AG will this work now im getting all kinds of codes po 031 po 037 po 443

We ran battery down. Then a guy jumped us, the car started and quickly died again for three times, like there was no gas. Then guy kept trying to start till the key when turned would not even make a noise when turned to start, nothing happens. He then got under truck and jumped the starter, it cranked fine several tries but engine would not fire like it was getting no gas. I disconnected negative terminal for 20 minutes reconnected and used my fully charged Stanley 300 amp jump starter. Turned key nothing no sound except a load low clunk each time. Tested battery, it showed good, battery is old , terminals were corroded so I cleaned them good with baking soda wash. Reattached tried to jump with Stanley, nothing. Checked all fuses, nothing blown. What do I do? What if I but we battery and still it won't crank?

The problem occurs over time I drive with A/C on.

It has shut down 4 times on highway. The plugs and pcm were replaced new. It bucks then check engine light comes on along with throttle red lightening bolt. It is not throwing any codes and dealership does not know problem.
