1994 Ford Ranger Won't Stay Running

Video 1 of 2
--------------------------------------------------------------------------------­----------------------
My name is Ryan. I own a 1994 Ford Ranger XLT 4.0L 4WD 5 speed. I just bought the vehicle about a month ago and I am slowly starting to fix it up. It has ran good since i bought it and I check the fluids often. My problem is that I am unable to keep my truck running. For the past week I have parked it on a hill, the front of the truck facing down the hill, and I went to start it up and move it. I got in and i turned it over and it didn't start. That was normal. Turned it again and it started up. I sat for a minute and i coasted down into my friend's driveway. When i stopped in the driveway i put it into reverse and with the clutch still in the truck died on me. I threw it into neutral and started it up and started to reverse back into my drive way. I was able to get it into most of my flat driveway until it died. Once it died I was unable to keep it running. I could turn the key and i could watch it grab as the rpms started to rise to about 300 but it then died. so i pushed it all the way onto my drive way. I had work so I let it sit. The next day i had sometime so i slowly tinkered with it. I tried to start it and well i was able to. I started it and the rpms shot up to a little over 1500 as it normally did. Then it throttled back to about 800 and then it started to drop. As if it could not stay there. So i went online and read some common problems. Dirty IAC and dirty MAF. So i bought some cleaners and I cleaned them both. The IAC was very dirty. I placed them back on and tried to start it. It started but then died again. A friend suggest a clogged fuel filter. So i went and grabbed a fuel filter and a IAC, having the hopes it would work. I installed them both and at first i had the same symptoms, start then die, but I finally got it to start. Once started I was able to have it idle but it was very low. About 600 RPMS. I shut it off and started it and it worked fine. I was happy and thought I solved it. Today I went back out after it has sat for over 14 hours and tried to start it. I went in and turned the key and it started. rpms shot to about 1500 but then started to throttle back to idle. it then found the low idle about 600 rpms but then died after it sat there for about 5 seconds. I was worried. I then started it and kept the rpms high with the gas pedal. As i was holding it at about 1500rpms the truck started to chug and slowly die. i then sat for a minute with it off and tried again. I got it to start and sit at about 600 rpms but when i would give it any gas it would try to bog out. I am thinking it could be a fuel pump but there are many things it could be.. I do not have a check engine light on. Please help me. I just bought it and I really don't want to regret it. I know i need a new clutch since it has begun to slip. I checked the air filter and it was horrendous. I cleaned it out but I still need a new one. It was running fine when it was dirty so I don't think it is causing the problem. Need any more information please let me know.

Thanks,

Ryan.

in this video I added no Gas until it stalled. After that I started it and held it above normal rpms. as i held it, you notice the rpms drop on it own.

sensor issues most likely. happened to me on both mass air flow and dpfe.

[proximxr]

Crankshaft position sensor. It's giving incorrect readings under 1k RPM, causing the injectors to open late, causing a very rough and choppy idle, Once you get your truck warm, it runs fine, correct? Or if not fine, but having an idle that fluctuates 200rmps or so?

I have a 98 but it dose the same thing and I've bought 3 brand new mass air flow sensors and some other parts but it still never ran I don't know what else to do

I have a 1994 Ford Ranger 4.0 that's doin the same thing. I changed the MAF sensor and it did nothin. I then cleaned the IAC valve and the throttle body and still didn't fix the problem so today I put the code reader on it with the key on the run position without my truck cranked and the computer gave the code reader a 33 code which is basically the EGR valve is stuck open so tomorrow I'm goin to clean that and I just found out I got a bad vaccuum hose at the Throttle body. HOPE THIS HELPS

i am starting to have the smae problem please tell me if u kno what it is (I HAVE THE SAME TRUCK TOO)

Also try checking the Mass Air Flow (MAF) sensor.

[cnrails]

I would try a fuel pressure test first. If it is not a fuel pressure issue try the idle air control valve.

@Shitheadbballer13 There is no choke on a 1994 ford ranger, it's fuel injected.

[Shitheadbballer13]

check the engine temperature sensor. When its broken it will constantly read the engines temperature at either super hot, or super cold. So the choke valve is either open fully or basically closed, which will make your truck not stay on like that and shake
