somthing may be wrong with the security. is fuel coming out of the other injector? if it is then you may have a security issue.

Heres your wiring diagram it shows the complete heater wiring. hope this helps you,

Carb needs rebuilt, Auto choke not working properly. Be easy on the starting fluid you can easly blow a hole in top of piston.

Bad news. Depending on what your mileage is, you can have a burnt valve, sticking lifter, bad piston ring all on the right side of the engine. The blue smoke is burning oil. Oil from the crank case is being compressed up into the cylinder and being burned. You will have to get a compression check on that side of the engine. You check the compression one sparkplug at a time while the engine idles. A loss in compression will tell you what cylinder is failing.

Good luck and thanks for your question and I hope my suggestions help. burdfrenzy

If it's a V8 then it's 18436572

either the float is sticking, when it is running use the back of a screwdriver and rap the bowl and see if this helps, or the jets need adjusted, start with the right one first, turn in untill the motor starts to lag then open it up untill the rpm stops climbing, do the same with the left one also, see if this helps. let me know.

you have cross connected a battery feed with an ignition feed. Go back and check to ensure that all the engine harness connectors and any other connections made to the engine are correct.
If you have to, disconnect each connector in turn until you find one that shuts everything down, then recheck the wiring codes etc to enure you have plugged it into the correct connector. It is very easy to reconnect a harness connector into the wrong place so check wiring colour codes etc.

is the crank and cam aligned and the motor #1 cylinder on top dead center? Slide balancer on crank then all you do is put the new mark on the balancer at the new timing chain cover 0 mark. Or take the old tab and mount to new cover.you can look at old tab and measure the degree from zero, and when you make your new mark with a stone pencil and you put your timing light to it and set it for that distance btdc.

why dont you just put the alternator from the old motor on.

the big brain

you need to change the float in the gas tank because its not working right.

Take a voltmeter to the battery while truck is running. Should read 12.8 to 14,6 volts - that'll prove your alternator is working. My suspicions are your battery is tired and just not holding charge as deeply as it once did.

this sounds like you may have a head gasket that is leaking. you will need to have the compression on the engine checked when it is cold to see what is going on.the smoke is from coolant that has leaked into the engine and is being turned into steam and this is what you are seeing and once it warms up the leak seals off and should stop smoking

8 degrees BTDC engine warm & 700 RPM.
distributor vacuum off & plugged. In drive, & accessories off.
Don't forget parking brake on.Hope this helps!

Short answer, yes. It is to reduce the chances of a vapor lock forming by returning vapor and hot fuel back to the tank and keeping cool fuel circulating through the pump.
