Hope this helps.">
1 sensor drives the temp guage in the dash.
The other sensor tells the 'computer' if it is a cold start or a hot start. Which makes a lot of difference in how much fuel is injected. This sensor is bad. If the truck is hot, it starts fine. If cold, not so fine. The sensor giving the problem has 2 wires, and usually are a black and yellow wire twisted together. Replace it.
Check the relay/s.
could it be the bran , icm module has a good ground it has fule pressure just no fire,checked all wires with ohm meter no shorts
With a 4 cyl in it & I had the same prob with it starting that Ya'lll R having. And I found it 2 B the Module's ground. The Mod looked ok & didn't give any code into the computer. But I pulled the Mod off & checked the back & it was all caroded. I cleaned all of it off & cleaned the three mounting holes because they were also full of crud. Then I replaced the insulating jelly & reinstalled it & have had no problems since. I checked every idea from this sight first. Then went to a friend who owns & runs a repair shop here in North Adams Ma. He has a Computer Program He pays for that he types in a problem & it runs many different sens & it gives every option to try before you spend hundereds of dollers & spend hours looking. It's a real time saver. But if any of Ya'll want 2 try this idea of the Mod B my guest I've done it on 2 other Ranges & it's worked well. So good luck
-Leaking fuel pressure regulator lets vacumn line fill up with gas after shutdown and this causes hard starting.
before i knew this, when it did stick a simple hard bump on the relay box allowed the truck to start.
Sometimes its the simple things.
It won't start occasionally. Turns over, but won't fire. Leave for a few minutes and most times it will start. The other night, it wouldn't start after trying for over 20 minutes, but when I returned next day, fired up immediately. It doesn't seem to affected by cold, as sometimes it happens in the garage and other times out in the open. A couple of times, it has happened after initially firing, it stalls and then won't refire. Wait 5 minutes, it starts ok. I have started to charge the battery every few days, as this seems to keep it working okay. With the battery fully charged, I can go almost a full week before it won't start again.... the battery is good, new last year and checked 2 weeks ago by a mechanic. I had fuel filter changed when I sent it to mechanics 2 weeks ago, as it wouldn't misbehave for them, and I was desperate to try something, but it didn't solve the problem... Any suggestions? The mechanics are of little help.
What about fuel pump pressure. Has a mechanic put a pressure gauge on the fuel line while cranking? Not sure of the pressure needed, but it's probably 40 pounds or more.
Any one with an answer?
as far as the starting problem goes; i was recently in cold weather with my 93 mazda b2300 (same engine as a 94 ford ranger 2.3 L SOCH) and i started it up, ran fine for about 5 minutes. Stopped at an intersection; went to disengage the clutch and the truck died. I tried cranking it over; but it wouldn't start. I have been in weather below 0 degrees with this truck and its started up and ran perfect every single time; so this would be kind of alarming to me at first. I have spark; my fuel pump works and i have pressure going to the fuel rail. So; what I did was went to the parts store; got some starting fluid and HEET. Get this, I walked back to the truck, took off the intake thought, "hmmm..maybe it will start" and you know what? It started; but it was shakey to hold idle at about 800 rpms, so i poured the whole bottle of heet into the full tank of gas and it took about five minutes for it to work through the engine to remove all the possible moisture that might have condensed in the fuel system.
Also, under heavy acceleration I hear what sounds like a knocking noise coming from the engine compartment. I think it has something to do with the cold start system taking air from the exhaust and blowing it into the air intake; could it be a short causing the cold start intake system to engage when the engine is running?
Any suggestions/ thoughts?
