Question about 1990 Ford F150

1 Answer

1990 f150 5.0 wont start

Changed a bad water pump. repair went well. was putting it back together, smoke came from 2-3 places under the hood at once, then stopped (key switch was on for the radio to work). It did this while I was standing next to it, not actually doing anything at the time. Had no wires disconnected, nor any tools on top of battery. It just smoked, then quit. Now, it cranks, but no start. Checked all the fuses in the panel under dash, all appear good. Are there any other fuse panels or breakers I need to check? Any ideas on what to check are appreciated.

    replaced Ign coil and ign module on distributor. went from no 12 v in the ign coil to intermittent 12 v. Spent several hours cutting open wire harness to find a broken wire inside the harness. Thanks RoyinGA, you were exactly right!

If the key was turned forward you burned the coil out or even the ign. module

    yea moving the wires around could have messed up the connection did you clean them or just cut them out and splice? Either way you need to make it water tight to avoid the corrosion. I always cut and splice and use a little dielectric grease and heat shrink splices

Mercury sable 1996 changed fuel filter had brown gas in it did this ruin fuel pump. Can hear pump when trying to start car


Most likely the fuel pump is ok, but there is likely air in the fuel line that you need to bleed off under the hood.

It is possible that the fuel pump went bad, and the way to know is to check the fuel pressure (same place you bleed it under the hood). The fuel pump is in the tank, so it's a real pain to change.

I have a 1997 buick lesabre, and it wont start. I took it to a guy who said that it was the fuel pump. well he changed that but it back fired a couple of times and then it stopped and wont start again. It's just turning over now. well then I found out that the gas I put in it may have had water in it, when the guy went under the hood and pushed out some "gas" it was water it had no smell. so we put some rubbing acohol in it to burn out the water. now it still wont start. I need help, dont know what to do at this point. PLEASE HELP SOMEONE!!!!

My s 430 has smoke coming from under hood after driving but not all the time temp gauage reads normal. I had oil and trans leaks sealed but it is still happening, what else could it be? Thanks


SMOKE UNDER HOOD COULD BE COOLANT LEAK FROM RADIATOR ITSELF OR CHECK FOR LEAKING TOP RADIATOR HOSE AND CHECK FOR LEAKING BOTTOM RADIATOR HOSE.LOOK UNDER THE HOOD IF COOLANT BOILING OUT COOLANT OVERFLOW JUG ENGINE OVERHEATING FROM BAD THERMOSTAT OR BAD WATER PUMP.CHECK FOR COOLANT LEAK AT WATER PUMP WEEP HOLE.IF SO WATER PUMP NEED REPLACING.ADD MORE COOLANT UNTIL LEVEL CORRECT.TRY LOCATE LEAK. IF CAR OVERHEATED AND BOILED IT OUT. SMOKE UNDER THE HOOD CAN ALSO BE CAUSED BY LEAKING VALVE COVERS WHICH CAN BE FIRE HAZARD IF OIL LEAKS ON HOT EXHAUST MANIFOLD.

My car overheated instantly and then it had a grinding sound when i tired to start it. It will start at all. Could a bad water pump cause it not to start? Or, what's the problem and how do I fix it?


the waterpump may have went out, leaked out all the coolant, and depending on how badly you overheated your engine, you may have serious problems as to some engines dont handle extreme heat very well. you might want to get professional help

2000 Jetta is Leaking antifreeze and smoking


I think you mean you saw water vapor (some call it steam) not smoke.

You probably have a hose leaking (badly). If it's not a hose, your water pump shaft seal is probably kaput.

Water not circulating,we put on radeator cap water pump ,intake gasket,flush heater core,engine radeator,reservoir


check to make sure the bottom radiator hose is not collapsing. sticking together. once it sucks together its like the thermostat being closed. the faster the engine turns the it sucks together. also make sure its not the clutch on the fan gone bad. if it has one. to ckeck ,look under hood at fan ,have someone to rev engine. make sure the fan turns as fast as the engine turns . if it doesn't it's a bad fan clutch. goe put a new one on.

Bottom wheel of water pump wont turn, burning belt


The wheel could be stuck but you need to have the water drained out and a mixture of antifreeze to water added to it. Be sure to keep in mind the heater core also has fluid in it and you could damage that also.
