'89 Jimmy, 5.7 TBI, rust on the fender, flames on the hood, worn out tie rod ends
I know the last few details weren't germane to the topic and the picture was totally unnecessary, but everybody likes to look at pictures. So I did something really stupid...I ran my '89 Jimmy pretty much out of gas last weekend. Ever since then it has been running a bit rough and stumbling under load. Seems to be much worse when the engine is warm. I've changed the fuel filter already, and it sounds to me like a fuel delivery issue, but I'm not looking forward to dropping the tank and replacing the fuel pump (I'm assuming pump got some crap in it and is going bad). Just wondering if anyone out there has any troubleshooting tips before I drop cash on a new fuel pump. Thanks in advance for your help.
