1989 7.3 replacement starter
Hey guys, getting back to my IDI this summer, been a few years since I drove it. Having trouble getting it started, replaced the fuel solenoid last summer and has fresh 850cca batteries. I do need to bleed the fuel system and replace the water seperater on the fuel filter(has a small leak). Not sure if that's a gasket or something else causing the leak. Besides that it seems to crank slow and not fire up. The glow plugs are working and have motor craft glow plugs in it. They stay on approx 8 seconds then go off. I'm thinking a new starter will help.crank it faster and stronger. It's the original from 1989. What is the best starter? Should I go with the gear reduction style? Thanks

Fresh batteries but are they fully charged to 12.6V? How are your cables and connections? Where is the weak link in your slow starter? The solenoid? Your engine should turn over adequately with a stock starter.

Cables are stock, not corroded or broken. Batteries have been on a trickle charger and charged up. The solenoid works since it engages the starter. Am.o missing something on the solenoid function? I'm suspicious of the starter since it won't even cough to life with ether. I'm getting fuel at the injectors since I've cracked them and pushed fuel at each one. It has an E4od or id pull start it

When I'm installing a fully charged battery I always clean the terminals and cable connections with a terminal cleaning tool you can get for 5 bucks. Then make the connections. Clean and tight is right. Cables should be free of corrosion and properly treated with grease to prevent corrosion.

Do you have a DVM? Take a voltage reading on the trickled batteries. I always disconnect the battery before charging and a 10 amp smart charger would be better than a trickle.
Before charging a battery always check the cells for proper electrolyte levels and top off with distilled water.

Depending on the miles the starter maybe is getting tired. I had to replace the original in mine at about145k miles. It just got slower and slower. I went with the powermaster 9050. The only complaint I had was the battery terminal would not bolt onto the starter, as I recall the cable had a 90 degree bend and needed to be straight. I made an adapter which work. About 6 months later the positive cable on the passenger side battery decided to give up, It was corrioded inside the terminal. Cranked fine and the next try was totally dead. So I replaced those cables with ones that fit first generation power stroke as they were a few inchs longer. Have had no issues since. Certainly spins fast. The regular starter should be fine also.
