Ok so i have a 2000 honda civic lx.... about four days ago i started my car and the lights were very dim. not long after i noticed my d4 light started to blink and my check engine light come on. after about two minutes of driving my car started to not accelerate... i was hitting the gas but she wasn’t moving really. almost like i was in neutral. also when i shift to D4 my car does this big jump it shifts really hard. so i parked at a gas station because i couldn’t drive back home. i noticed my windows wouldn’t roll up. at the time i had googled and it seemed i was low on transmission fluid. long story short the car eventually wouldn’t crank anymore after about 20 minutes of sitting. i had her towed back home. the next day i put oil and transmission fluid. still same problem. i got a jump, and after the jump my car cut off in about 2 minutes. still have the acceleration problem as well. anyways, i had alternator replaced. no change. had ELD replaced. same problem. NOW i’m being told it’s the fuel pump.. gas anyone had this problem? i’m tired of spending money on parts and it not fixing the problem

Sounds like either a transmission issue with a secondary charging system issue.

or

an electrical issue causing multiple issues including the transmission problem.

-Flashing D4 means that there is an issue with the transmission.

-dim lights/windows not going up, means they aren't getting enough current/voltage.

Are you planning on trouble shooting the systems yourself; if so we can help? If not take it to Honda for an inspection.
