#1 of 6 Bronco II cold start by Bronco_Bob Feb 14, 2009 (7:26 pm)
I have a 1988 bronco II. When the out side temp is below 32 degrees F it fires once and will not start. But when the temp is above 32 degrees it starts fine I have added HEET to the feul it does not seem to be helping Replies to this message: tidester (Feb 14, 2009 8:24 pm) Bronco_Bob (Mar 10, 2009 6:18 pm)

Replying to: Bronco_Bob (Feb 14, 2009 7:26 pm) It sounds like your engine's not getting enough air. Try holding the pedal to the floor (don't pump) when starting and see whether that makes a difference.   tidester, host SUVs and Smart Shopper Replies to this message: Bronco_Bob (Mar 10, 2009 6:18 pm)
#3 of 6 Enbgine loses power almost like plugged filter by Bronco_Bob Mar 08, 2009 (5:56 am)
My 1988 Bronco II was running fine when the engine began to lose power almost like a plugged fuel filter. The filter was pretty full so I changed it and then it ran for a week (about 100 miles) then it did it again it stopped 5 minutes after starting it. I messed with it for awhile that it started running again it ran down the highway for ten minutes the it stopped again. The weather was about 70 degrees and sunny so it is not freezing up. The took off the line at the filter and there is fuel there. then I took the line off the fuel regulator there was no fuel there. The only thing I can think of is the high pressure fuel pump. It that what it acts like when it goes out? Replies to this message: wpgjuggalo (May 18, 2009 11:05 pm) Bronco_Bob (May 19, 2009 7:24 pm)

Replying to: Bronco_Bob (Mar 08, 2009 5:56 am) hook up a fuel pressure guage and watch it... Chances are the high pressure pump located on your frame rail is toast. It will run while it is cold but once the pump heats up it will fail... Replies to this message: Bronco_Bob (May 19, 2009 7:24 pm)
