So I bought a 1991 ford ranger 2.9 v6 and can not figure out what might be wrong with it. any help would be great. This is what i have done. In this order
New battery New spark plugs New fuel injectors New fuel filter New Cap and rotor New coil
So i started by getting the new spark plugs since the old ones looked bad. Cleaned the fuel system and put new injectors since the person i bought the truck from said that a farm helper had put some diesel in the truck and thats what started the issue. Checked that there is a ton of fuel at the rail by pressing the tire fill looking vale. sprayed a lot for a few seconds. checked that i have spark and i do. Took a plug out and turned the motor with my finger trying to plug the hole just to see if i have compression and i do. Would not start. my grandpa and step dad thought it might be the timing so we tore it down and checked the chain alignment. right on the money. so i have spark fuel and compression. i thought it might be the spark is not strong enough so i got a new coil, cap and rotor. also bought a distributor but the one i got from a junk yard would not fit for some reason so i am gonna go get another this week and try that even though i do have spark. Maybe the module which is attached to the distributor is the cause even though i have spark. who knows. when i had the timing cover off i also replaced the water pump because the old one looked bad. i just dont understand what the issue could be. So another suggestion was to try and get it to go on starting fluid. No help. I feel like i am at the end of what i know could be an issue. Plenty of air since the air filter is newer and even if i take the intake hose between the throttle body and air cleaner box (air cleaner box houses the mass air flow sensor) to inject the starter fluid i still get nothing. The worst part is it will run for a brief moment after a week of sitting out at my grandpas house but run poorly and only for about 5-10 seconds.
So here are a few questions.
- if the motor has compression and spark and the firing order is right 1,4,2,5,3,6 and i am at tdc and the order starts on the right place on the cap then should it start when the intake is taken off and the starter fluid is injected into the throttle body?
- i have found a person who helped determine that i have 6 injectors that fire three at a time and that they are also right. so i didnt cross any wires when i installed the new injectors. Can i verify the fuel is making it to the cylinder in the correct order?
- Where else can i go with this?
I am hoping that i do not have to run down to the local Ford dealer and have them put it on a scope because that is 80 dollars i do not have but i am kinda at the end of what i can think of.
Please help me. It is a b day present from my wife and we can use a truck. (who cant)
Thanks for looking and trying to think of a solution.
