20 Most Recent 1988 Ford Bronco Questions & Answers

Check fuel pump pressure. First shoot a little starter fluid into the throttle body to see if it runs. If it does, fuel delivery problem.

I saw some bronco bench seats on ebay, they are expensive. I just did a web search. Other than that, I don't know? Call around to some salvage yards?

Map sensors can't be cleaned. When a Map sensor fails, it usually causes the injectors to dump way too much fuel for the altitude and the catalytic converter gets overheated. The sensor reads the amount of vacuum present in the engine and adjusts the amount of fuel the engine needs to run as the altitude changes.

I have no idea about OBD... evolution (Jumped from '75 Ranchero to 2004 Navigator...) but I had similar troubles due to cold start valve... Whatever FI emulates a choke... I'm assuming you have fuel injection.... ROCKAUTO shows both Carby & Fuel Injection options... but your symptoms are pointing to FI... (see below). Check out your diagnostic capabilities to see if you have any TROUBLE CODES... then start with the cold start (air?) valve ... then onto the injectors themselves (if equipped) ((Just sounds VERY FAMILIAR)).. Also try looking up your TSB (tech service bulletins) on BBB Industries site (Free: registration required) BBB Industries Premium Alternators Starters Power Steering Products http://www.rockauto.com/en/catalog/ford,1988,bronco,5.8l+351cid+v8,1105928,fuel+&+air

Probably a loose or missing vacuum hose. Check the vacuum diagram under the hood and look for loose or cracked hoses.

One in the tank. If it has 2 tanks it'll have one in each tank.

I like mine at 800 RPM+, it moves coolant better through the system and spins the alternator a little faster for running heater and lights.

Fuel filter. Low fuel no power. Catalytic converter. no air out, no air in. loss of power.

The scissor mechanism inside the door may have failed causing bad alignment.

I believe your Bronco has a 4x4 actuator which often fails. Not a cheap part, but pretty easy to replace. Buy a parts store shop manual and it should show how to fix this. Might also check wiring to the unit and all fuses.

check that you have installed the gear lever in the shift rail when you refitted the lever tower on top of the box

If it has push button 4wd then tap on the transfer case actuator lightly with a hammer to get it to disengage.
