So I as driving along to school one day, and after I passed over a bump, my 1996 LS400 died on me. We checked the fuel pressure and it was normal. After going over the bump, the car would not start. The distributor caps are brand new, the spark plugs are brand new as well. We replaced the fuel pump ecu capacitors with no avail. We tested the ecu in another ls400 and the car started and worked perfectly. Now the car will not accelerate , but it idles. Im open for discussion.

p.s it has 201000 miles

sounds like an electrical short or open - do a careful visual inspection at night, wearing a bright headlamp with a tight beam

have you checked all fuses (inside car and inside engine compartment), as well as fuse links, relays, and circuit breakers?

have you scanned the car for codes?

All the fuses are good, and its bringing up no codes, I suspect its the MAF but I dont know Im not a mechanic
