Exclamation Help! Wouldn't start this morning.

I have a 94 ranger 5spd 2.3L. This morning the temp was about 7 degrees. Yesterday was the same temp and my truck started fine. The only thing I did between yesterday and today is drive to work and fill up the tank. Last winter I had a problem with cold starts a couple of times but it always started. It would start after 5-10 cranks, idle rough and smoke like a diesel, and then run perfect when warm. When it's over 10 degrees it started fine. Over the summer it ran good and then this fall I noticed my idle would go up and down up and down. This only happened like once a week. Today when I started it it would crank and crank but no fire at all. I did notice an excessive engine vibration on each turn but thats it did that last winter when I had problems too. The truck has 230,000 miles. Please help because this is my daily driver!

Well we can rule out the battery and alternator since you clearly have more than enough electricity to crank it over and over and over. The vibration is probably incomplete combustion. It is firing enough to shake but not do anything else. This also explains the gas dumping out the tailpipe.

When you turn the key to ON (not start), do you hear the fuel pump kick on and whine for a few seconds? If not, check the fuses related to the fuel pump (check the manual for fuse numbers). If you do hear the fuel pump come on, then I would move on to checking the fuel pressure under the hood. There is a little schreader valve under there somewhere that you put a gauge on to test the fuel pressure. I believe it should be somewhere around 30 or 60 psi. Someone else will have to confirm the location and actual PSI. If the fuel pressure is low, the pump is probably going out. Cold weather can exaserbate a failing pump. Also, this would be a good time to change the fuel filter if it hasn't been done in the last 30,000 miles or so. Especially if your seeing pressure issues.

If fuel delivery is not a problem, that takes us to spark. Pull a spark plug, ground the side of it to the engine block, and start cranking. You should see spark if it is working. I'm not expert on the 2.3L so I'm assuming you can do that with those things. If you're not getting spark, someone who knows 2.3L ignition systems will have to take over on that one.

In addition to firerangers suggestions. Do you do regular maintenance.
Air filter, fuel filter, pcv, plugs, clean tb, maf? Idle air control valve. Any CEL?

I suspect the engine vib might be power steering related. Suck the fluid out replace with mercon, drive, repeat. You might need a new PS pump or serp belt

----------

Plus you could have gotten bad gas.You can pour fresh gas or spray starter fluid into the TB. Also check and make sure the timing belt is not broken

I will check spark and fuel when I get home after work. The air filter, fuel filter, and spark plugs have all been replaced recently, and I usually run some injector cleaner through it every couple of months. As far as hearing the fuel pump kick on, it is pretty quiet (I've never heard it even when the truck was new) so I'm not hearing it. I've never cleaned the MAF, EGR or IAC so I will go ahead and do those tonight anyway (O thats going to be cold!). PCV's are cheap so Ill go ahead and buy a new one today. Have had the check engine light for about 5 years. Got it when the tach quit working and I'm not sure if its the crank position sensor or cam position sensor. Napa and autozone couldn't tell me either so I haven't fixed it.

Remember to check the TIMING BELT. Also as fireranger said suspect fuel pressure. You want about 40psi=koeo, 30psi=koer the pressure should go up when you pull the VL off the FPR. Also you could have bad gas. Finally you can pull the vacuum line of the fuel pressure regulator. It is on the fuel rail. There should not be gas in it. Keep us posted

If it is cold you might want to concentrate on spark, FP and timing belt. You can put a rag over the shrader valve and carefully push the valve in to see if you have pressure. It also could be the Crankshaft PS

It started last night with no problems. It was about 15-20 degrees. This morning it was about 15 degrees and when I started it i got the same symptoms as yesterday but after a second I floored the gas pedal and it started up. So if it ran last night and today my timing belt must be ok. Im thinking it must be a fuel problem. I didn't check anything last night because it started right up so I don't wanna tear into it until this weekend (during the week I live 50 miles away from my heated garage and all my tools). So hopefully it will run until Friday when I have a good chance to work on it.

i would get some sort of engine heater and plug it in 2~3 hours before you need to go some wear

Other than wasting electricity, this will do nothing to hide or fix the problem. The actual problem needs to be found and fixed. Fuel pressure is still the most likely based on these symptoms.

Iagree with fireranger most liky a fuel isse or a dirty or malfuncing. IAVC. Clean the IACV. ASAP

Didn't start this morning. Hoping it will start tomorrow so I can get it to my shop and check everything out.

Ran fine all weekend but wouldn't start today. This weekend I cleaned the maf and iac. I also replaced the pcv. I found the line from the header to the egr broken and my egr was very dirty and coroded so I plugged the line that goes to the intake with a Dow rod to get me to today. I am going to a junkyard today to try to find s better egr and line. Also I may check my fuel pressure if I have time

Ok I checked the fuel pressure and tried a different egr(didn't help). The fuel pressure reads at 40 psi when I first turn the key and drops slowly to zero with the key still on. But when I crank the motor over to start it the fuel pressure holds at 40 psi as long as I crank it. I don't know if this is normal or not. And also my tach hasn't been working for 3 or 4 years, if it is my crank position sensor that runs the tach could that be a culprit. I'm not sure if the cps would be effected by weather temperature?

The CTS coolant temperature sensor send signals to the ECU (computer) telling the engine how hot it is or isn't allowing the computer to send the ignition signals to advance or retard the timing to allow your car to be more efficient. When it goes bad it will and can cause the following conditions:
no start when warm
no start when cold
crappy gas mileage
crappy idleing.


idle flux is usually/common (on lima engines) caused by EGR

Ok is there a good way to test this CTS sensor? And also I just tried starter fluid in the throttle body to see if there would be any response and there was no difference at all. I don't really have to tools to pull the plugs (And I don't think I could get them out anyways because I can't function well at 0 degrees).
