No power to fuel pump

carb --vapor locked --fuel filter ---switch over valve failure

did they replace the engine temp sensor? it could be open and the computer sees -33 thinking the engine is cold and dumping fuel.

Look at your registration, note "model year" If you ar still unsure, call a Ford dealer and ask them to look up your vin #. They will know for sure.

Sound like an ignition issue.The hotter temps are causing a part to fail.If you've never replaced the ignition coil,this is the easiest place to start.Another possibilty would be the pickup in the distributor,or the reluctor on the distributor shaft.

does it sound like it cranks funny if so r u sure that it hasn't jumped time maybe not but if u have to spray starting fluid in it t get it to run then then either the injectors aren't opening (obviously ) lol

when u put the distributor in r u sure u have it in time and if u r sure u did then have u got someone to crank it while u turn the distributor a little from left to right and see if it will start

also check all ur grounds under the hood and make sure they r all intact especially the grounds going to the neg battery terminal

Well if he caused a short in the electrical system it could be the eec relay it is located on the passenger side under the hood on the fenderwell. Some are marked with what they do there can be 3-4 relays on it, the relays look like a small box with a connector at the bottom, and quite a few wires coming out. the one for the eec relay should be in the middle it was on my fathers 88 bronco 2. the fuel pump relay is the same thing, there cheap to buy and can find them at the parts store they are known for failure, just replace it..

fuel pump

sounds like it could be the relay. also this one has 2 pumps I think, one in the tank LP and one on the rail just under the driver. 2 relays also one for each.

spray starting fluid in the intake. if it starts it's fuel problem, if it does not it's electrical. could be bad fuel pump or crank sensor

if the fuel pump cutoff was tripped it would not start at all, I know this for sure, I am a Ford dealer tech and I specialize in no starts and check eng lights. If the ignition switch is bad the 2 halves of the switch will be starting to come apart, it is very common, u should be able to either see it or feel it with your hand.
