1994 Ford Ranger, Rough Cranking When Engine Is Warm/Hot?
- 1994 Ford Ranger
- 2.3l Engine
- 110k Miles
My truck has been having problems cranking when the engine is warmed up/hot. When the engine is cold or hasn't been started for like 2-3hours, it will start right up.
I have a few ideas of what it may be, but I would like others opinions also.
- ECT Sensor?
- ICM?
- Crank Sensor?
Those are the three I have thought of that could be causing a problem with my situation.
If you mean rough cranking by the starter drags when tryin to start engine after it has warmed up check this. Check battery cables, engine ground cables, and cables attached to starter. Check for tight connection and corrosion.Repair if necessary. Get battery tested, this can be done while the battery is still installed. If its good, the starter is getting ready to go completely out.Remove it and have it tested. If you mean, the starter turns over fine but it has to be cranked continuously in order to get the engine started(hard starts)check this: A clogged fuel filter, defective fuel pump, or faulty fuel pressure regulator can cause hard starts. The map sensor, faulty or clogged egr valve or pipe, bad evp sensor(bolted to egr valve)faulty ignition module, or dirty maf sensor can cause hard starts.Remove maf sensor and spray electrical contact cleaner on heated wires, let dry, then reinstall. The egr valve can be cleaned with carb cleaner.Autozone can test ignition module if you remove and bring to them
- Why does my Ford Ranger start rough idle when engine is hot? I have a 2002 Ford Ranger XLT 4X4 with 4.0 litre SOHC engine, it starts good when cold, but I get a rough idle start when the truck was already used and heated up. Engine diagnostics show nothing, I changed the air filter a month ago, changed platinum plugs and plug wires last year, regular oil and filter changes been done. I'm running out of ideas on the cause of this rough idle. Any suggestions, please answer.
- Ford Ranger 4.0, 172,000 miles rough idle when starting after sitting overnight or after 2-3 hours. Starts 1st crank, idles rough 1 minute? Or so and then smooths out and runs fine. New heads and gaskets. Cleaned MAF sensor, throttle body and air intake sensor, new IAC valve, new air and fuel filters, new PCV valve. No smoke coming from exhaust and No check engine light. Any ideas what's causing this rough idle?
- I need a battery for a 1988 Ford Msutang LX, hasn't ran in 16 years and I just want to get it cranking again? Hasn't ran in 16 years, and I want to at least get it raining again Mustang 5.0 8 cylinder, convertible. Looking for something cheap to start off with.
- I bought an Actron CP9125 Code Reader to try and diagnose a rough idle at cold start on a 98 Ford 4.0 engine. The rough idle had not caused? The CEL to come on. I plugged the code reader in with just the key on and pressed read and the little asterisk goes half-way across the screen one time and stops. I press the read button again and it reads 0 codes. I was thinking it would scan multiple times to check for pending codes or other issues. I tried it with the engine running and the same thing happens. Is this code reader operating properly?
